arm: fsl: common: Improve NXP VID driver PMBus support
This patch adds support for more PMBus compatible devices to the NXP
drivers for its QorIQ family devices. At runtime, the voltage regulator is
queried over I2C, and the required voltage multiplier determined. This
change supports the DIRECT and LINEAR PMBus voltage reporting modes.
Previously, the driver only supported a few specific devices such as the
IR36021 and LTC3882, so this change allows the QorIQ series to be used
with a much larger variety of core voltage regulator devices.
checkpatch warning "Use if (IS_DEFINED (...))" was ignored to maintain
consistency with the existing code.
