regulator: mt6358: split ops for buck and linear range LDO regulators

The buck and linear range LDO (VSRAM_*) regulators share one set of ops.
This set includes support for get/set mode. However this only makes
sense for buck regulators, not LDOs. The callbacks were not checking
whether the register offset and/or mask for mode setting was valid or
not. This ends up making the kernel report "normal" mode operation for
the LDOs.

Create a new set of ops without the get/set mode callbacks for the
linear range LDO regulators.
