[PATCH 4/6] mfd: qcom-pm8008: Add PM8010 support

[Jishnu Prakash]

From: Konrad Dybcio <konrad.dybcio@xxxxxxxxxxxxxxxx>

PM8010 is effectively the next generation of PM8008. The device is
generally designed to serve the exact same function - power camera
sensors and the associated supporting hardware.

PM8010 supports both I2C and SPMI communications. The latter case is
already handled, since it reuses the same peripherals as other PMICs.
The I2C front-end is more less the same to the one of PM8008.

Plumb in the necessary changes to support it.
