Add rockchip_ddr_set_rate to support ddr frequency switching.
This function wraps the SMC call and frequency switching is
implemented in ATF. Afterwards it will call clk_get_rate to
update the rate in clock framework.
Set dmcfreq->is_set_rate_in_dmc=true to enable this process.

Add the function of rockchip_get_freq_info to get available ddr
frequencies info via SMC call. The frequency info include available
frequencies count and frequencies table(sort by rate from low to high).
Afterwards it will update the dmc_opp_table base on frequencies info.
If have "system-status-level" property in dmc, the function of
rockchip_get_system_status_level will get the frequency for
system-status base on frequency level and available frequencies table.

When setting the 16550 serial port baud rate, you need
to configure the UART to loopback mode. After setting
the DLL and DLH, you need to reset the LSR first,
and then configure the MCR to make the UART return
to the normal mode. If you do not reset the LSR
first, an error will occur when the UART RX is still
receiving data.

There are some rates that would be ranged for better clock jitter at
Chrome OS tree, like 25.175Mhz would range to 25.170732Mhz.
But due to the clock is aglined to KHz in struct drm_display_mode,
this would bring some inaccurate error if we still run the compute_n
math, so let's just code an const table for it until we can actually
get the right clock rate.

The previous tables for mpll_cfg and curr_ctrl were created using the
20-pages of example settings provided by the PHY vendor. Those
example settings weren't particularly dense, so there were places
where we were guessing what the settings would be for 10-bit and
12-bit (not that we use those anyway). It was also always a lot of
extra work every time we wanted to add a new clock rate since we had
to cross-reference several tables.
In <http://crosreview.com/285855> I've gone through the work to figure
out how to generate this table automatically. Let's now use the
automatically generated table and then we'll never need to look at it
again.
We only support 8-bit mode right now and only support a small number
of clock rates and and I've verified that the only 8-bit rate that was
affected was 148.5. That mode appears to have been wrong in the old
table.

Dut to the high HDMI signal voltage driver, Mickey have meet
a serious RF/EMI problem, so we decided to reduce HDMI signal
voltage to a proper value.
The default params for phy is cklvl = 20 & txlvl = 13 (RF/EMI failed)
ck: lvl = 13, term=100, vlo = 2.71, vhi=3.14, vswing = 0.43
tx: lvl = 20, term=100, vlo = 2.81, vhi=3.16, vswing = 0.35
1. We decided to reduce voltage value to lower, but VSwing still
keep high, RF/EMI have been improved but still failed.
ck: lvl = 6, term=100, vlo = 2.61, vhi=3.11, vswing = 0.50
tx: lvl = 6, term=100, vlo = 2.61, vhi=3.11, vswing = 0.50
2. We try to keep voltage value and vswing both lower, then RF/EMI
test all passed ;)
ck: lvl = 11, term= 66, vlo = 2.68, vhi=3.09, vswing = 0.40
tx: lvl = 11, term= 66, vlo = 2.68, vhi=3.09, vswing = 0.40
When we back to run HDMI different test and single-end test, we see
different test passed, but signle-end test failed. The oscilloscope
show that simgle-end clock's VL value is 1.78v (which remind LowLimit
should not lower then 2.6v).
3. That's to say there are some different between PHY document and
measure value. And according to experiment 2 results, we need to
higher clock voltage and lower data voltage, then we can keep RF/EMI
satisfied and single-end & differen test passed.
ck: lvl = 9, term=100, vlo = 2.65, vhi=3.12, vswing = 0.47
tx: lvl = 16, term=100, vlo = 2.75, vhi=3.15, vswing = 0.39

Jitter was improved by lowering the MPLL bandwidth to account for high
frequency noise in the rk3288 PLL. In each case MPLL bandwidth was
lowered only enough to get us a comfortable margin. We believe that
lowering the bandwidth like this is safe given sufficient testing.

Most SOCS have only 8 or 6 channels, but have more than 16
peripherals. If those peripherals work together, some
fails to request dma channel, because there are no enough
channels. And maybe it's unnecessary to use dma for uart
tx. It is necessary for uart rx when hardware auto flow
control is not used.
&uart0 {
dma-names = "!tx", "rx"; // disable uart tx with dma
status = "okay";
};

To avoid "too much work for irq" issue, cherry pick the patch.
It reads the RBR to clear the time out interrupt, but sometime the
rx fifo may be not empty while cpu reads the RBR. Which would cause
the data lost.

By the way, current patch can't get rid of the risk entirely, so I
try a lot to solve it. Unfortunately, I only got the phenomenon that
lower pclk can reduce the probability. And I check the dw data sheet,
it has pclk and sclk, so there is synchronization problem. But it
only requires (slck < 4*pclk).
