Subject: [PATCH 3/9] regulator: max77802: Split regulator operations for BUCKs

Not all the max77802 BUCKs regulators have the same functionality, for
example BUCKs 2-4 support the output to be configured as normal or Low
Power Mode by the PWRREQ enable pin while the other BUCKs only support
their output to be set ON or OFF by PWRREQ. As a preparation for adding
a set_suspend_mode function handler for all the regulators that support
Low Power Mode by PWRREQ, split the operations for BUCKs regulators.
