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. Signed-off-by: Andres Salomon <dilinger@debian.org> Cc: Jordan Crouse <jordan.crouse@amd.com> Cc: "Antonino A.
