power: qpnp-charger: add support for external current sensing OVP

On some MSM8x26 platforms, board configurations exist which utilize
a current sensing OVP to allow adaptive input current limiting
to accurately measure the current flow through the external parallel
USB path.

Add support for this external OVP part by allowing an MPP to be
configured as a sense line and exposing the converted current
reading via a module parameter which is accessible to userspace.

msm: cpp: Provide cpp clock frequency table to user-space

CPP clock frequency table varies form platform to platform.
It have to be read and sent to user-space for cpp dynamic
clock calculation. It is done during GET_HW_INFO IOCTL
call. In result user-space sends current cpp clock rate
and bandwidth to be set up.
