The spi_enable_chip function takes a boolean
argument. Change the type to reflect that.

(cherry picked from commit 30688e4e67)
Let the dma/non-dma code paths handle the spi enable
flag themselves. This removes some logic to determine
if the flag should be turned on before or after dma
and also don't leave the spi enabled if the dma path
fails.

The dma direction for the tx and rx dma channels never
change, so just use the constants directly rather
than storing them in device data.

We no longer need the dma_caps since the dma driver
already clamps the burst length to the hardware limit,
so don't request and store dma_caps in device data.

The USB2.0 OTG PHY of RV1126/1109 which is designed for lower power
consumption provides only 8.8mA current source on DM. Multiplied
by 45 Ohm host termination resistance, voltage is about 400mV.
If the threshold voltage of host is greater than 400mV, the high
speed handshake will fail and SoC communicate at full speed. So
swing calibration is necessary.
We use gpio to control the 220 Ohm pull-up resistor to provide additional
current. Experiments show that the voltage of chirpK can be increases
to about 600mV.

Instead of open coding the polling of the lock status, use the
handy regmap_read_poll_timeout for this. As the pll locking is
normally blazingly fast and we don't want to incur additional
delays, we're not doing any sleeps similar to for example the imx
clk-pllv4 and define a very safe but still short timeout of 1ms.

The rk3036 pll type exposes its lock status in both its pllcon registers
as well as the General Register Files. To remove one dependency convert
it to the "internal" lock status, similar to how rk3399 handles it.
