The basic anx7625 driver only support MIPI DSI rx signal input.
This patch add MIPI DPI rx input configuration support, after apply
this patch, the driver can support DSI rx or DPI rx by adding
'bus-type' in DT.

IVO panel require less input video clock variation than video clock
variation in DP CTS spec.
This patch decreases the K value of ANX7625 which will shrink eDP Tx
video clock variation to meet IVO panel's requirement.

The driver originally use an atomic_t for keep track of the power
status, which makes the driver more complicated than needed, and has
some race condition as it's possible to have the power on and power off
sequence going at the same time.
This patch remove the usage of the atomic_t power_status, and use the
kernel runtime power management framework instead.

When suspending the driver, anx7625_power_standby() will be called to
turn off reset-gpios and enable-gpios. However, power supplies are not
disabled. To save power, the driver can get the power supply regulators
and turn off them in anx7625_power_standby().
