spmi: Rename qpnp library to be part of the spmi framework
It turns out that the only use cases for the qpnp library use
the existing spmi data structures. As such, there's really
no justification for having the library not be called 'spmi'.
There is nothing Qualcomm specific about this code.
Also cleanup some inconsistencies in the Kernel Doc comments
while we're here.
