cs5535: add a generic MFGPT driver
This is based on the old code on arch/x86/kernel/mfgpt_32.c, except it's
not x86 specific, it's modular, and it makes use of a PCI BAR rather than
a random MSR. Currently module unloading is not supported; it's uncertain
whether or not it can be made work with the hardware.
