Hi,
Mediatek PMIC chip have some spare registers used to store information.
The value of these registers will exist until user unplug battery or
battery depletion. One of our usage example is store battery utilization
in these spare registers. We want to implement NVMEM driver to
read/write sparse
power, so add pwrapper using USB power domain to
keep USB power domain not to zero and disabled.

Sascha sent similar patch before[0], but MMC support runtime-pm,
vcore power domain still be disabled after MMC and USB suspend.
This silicon bug already fix in MT8173

The mediatek SoCs have I2C controller that handle I2C transfer.
This patch include common I2C bus driver.
This driver is compatible with I2C controller on mt65xx/mt81xx.

Add mediatek MT8173 I2C controller driver. Compare to I2C controller

also increase message size to 64kb.
