Here is a fix for these warnings (only show up for 64bit so I missed
them, my fault again).

Subject: [PATCH] power_supply: twl4030_charger: fix compilation warnings

Registers are 8bit, so use proper type, fixing following warnings:
twl4030_charger.c:477: warning: overflow in implicit constant conversion
twl4030_charger.c:485: warning: overflow in implicit constant conversion

These only show up when building for 64bit target, so I missed them
while building only for 32bit ARM.
