This patch adds support for all current Qualcomm platforms which utilize
RPM over SMD. This includes both MSM8916 and APQ8084.

With the removal of VLAIS the size was incorrectly changed to only cover
the headers of the packet, resulting in "empty" requests being sent to
the RPM. Correct this so the entire message is transfered.

The BIT() was incorrectly inherited from family A and should not be used
on family B where the state is denoted by an enum.

The smd rpm structures are always in little endian, but this
driver is not capable of being used on big endian CPUs. Annotate
the little endian data members and update the code to do the
proper byte swapping.

Usage of VLAIS prevents clang from compiling this file, and it
also opens us to the possibility of allocating a large structure
on the stack to the point that we blow past the limit of the
kernel stack. Remove the VLAIS and allocate a structure on the
heap with kmalloc so that we're safer and more clang friendly.

Driver for the Resource Power Manager (RPM) found in Qualcomm 8974 based
devices.
The driver exposes resources that child drivers can operate on; to
implementing regulator, clock and bus frequency drivers.
