[PATCH 19/44] staging: mfd: hi6421-spmi-pmic: change namespace on its functions

[Mauro Carvalho Chehab <mchehab+huawei@kernel.org>]

Rename the functions used internally inside the driver in
order for them to follow the driver's name.

While here, get rid of some unused definitions at the
header file.
