Andres Salomon ab06aaf6a6 gxfb: create DC/VP/FP-specific handlers rather than using readl/writel
This creates read_dc/write_dc, read_vp/write_vp, and read_fp/write_fp for
reading and updating those registers.  It creates gxfb.h to house these.

We also drop a no-op readl() from gx_set_mode.  Other than that, there should
be no functionality change.
