Removes support for B0 revision silicon. The B0 revision is no longer

Adds support for the control port write-lock feature introduced in
revision B1. The write-lock feature minimizes the risk of spurious
I2C writes flipping sensitive bits during device operation by blocking
writes to some or all of the register map.
If desired, the write-lock must be set in hardware by biasing PGPIO2
appropriately and setting the cirrus,hw-i2c-lock flag in the devicetree
entry.

This commit should deal with the followings:
1. Change regulator's driver priority as it should now
be used by the clock control driver.
2. Check if the VDD level is permitted to change when PLL
is the system clock. This is because the PLL requires
that VDD be 1.2V.

For DA1469x if PM config is selected PM_DEVICE must also
be selected for GPIO to work when device enters/exists
deep sleep.
Previously GPIO and regulator drivers selected PM_DEVICE
when PM was enabled.
Now it is moved to SOC instead.
PM_DEVICE selection in GPIO could result in circular dependency
for mcux if MEMC_MCUX_FLEXSPI (which is already dependent on PM_DEVICE)
was to be additionally dependent on GPIO.
