Set pll_m_out1, sclk, and hclk to 120 MHz, and pclk to 60 MHz.
Drivers that require a faster bus speed can use a shared bus clock
reference to increase the sclk frequency up to 240 MHz, which will
also increase pll_m_out1, hclk, and pclk.

Move the flush_work outside of stop_tx, do it during suspend and
shutdown instead. Move the tty portion of the tx work into
the dma complete callback, and only handle polling on the fifo and
then requeuing the dma in the work function.

Get rid of dvfs_lock, replacing it with the cansleep flag on clocks.
Clocks with the cansleep flag set will lock a mutex before calling
into dvfs.
Also does the regulator api calls during late init, after the
regulators have been probed.

In the current implementation handles hold references to a
client and clients hold references to their handles. As a
result when a process terminates it's handles can't be cleaned
up and we leak memory. Instead only hold references to handles
from clients.

There is one wmb missing in the usb host controller driver after the queue head
update. Due to this data transaction is not happening on the bus after urb
submission by the hcd driver. Register updates/queue heads data in the memory
is not reflected on the AHB bus. After adding the wmb after queue head update
data transaction the USB bus started with out any delay.

In LP1 suspend, or during a failed LP0 suspend, the core power is
not turned off and the timer register is not reset. Saving the
timer value during suspend and adding it to the offset after resume
will cause the timer value to double for each suspend cycle.
To fix, when resuming subtract the current value of the timer
register from the offset. Also, use the rtc registers to add
the time that passed during suspend.

The 32k clocksource is never used, because it is always registered
at the same time as the us clocksource, which has a higher rating.
Using the 32k clocksource would cause a race condition with the
tegra_rtc driver on the RTC shadow registers. Remove the 32k
clocksource, add a replacement tegra_read_rtc_ms function for the
suspend code to track suspend time, and add a comment on
read_persistent_clock that it should never be called while the
tegra_rtc driver is running. It is currently only called from
timekeeping init, suspend, and resume.
