i2c: mv64xxx: Add atomic_xfer method to driver
Add an atomic_xfer method to the driver so that it behaves correctly
when controlling a PMIC that is responsible for device shutdown.
The atomic_xfer method added is similar to the one from the i2c-rk3x
driver. When running an atomic_xfer a bool flag in the driver data is
set, the interrupt is not unmasked on transfer start, and the IRQ
handler is manually invoked while waiting for pending transfers to
complete.
