After a warm reboot the REG_ASRCSR register may not be in its hardware
reset state. regmap caches the register value as 0 (the assumed default),
so when the desired clock source index is also 0, regmap_update_bits()
skips the actual hardware write because it believes the register already
holds the correct value. This leaves a stale clock source in the hardware.
Replace regmap_update_bits() with regmap_write_bits() so that the masked
fields are always written to hardware regardless of the cached value.

drivers")
