lxfb: create GP/DC/VP/FP-specific handlers rather than using readl/writel
This creates read_gp/write_gp, read_dc/write_dc, read_vp/write_vp, and read_fp/write_fp for reading and updating those registers. Note that we don't follow the 'DF' naming; those will be renamed to VP shortly. Signed-off-by: Andres Salomon <dilinger@debian.org> Cc: "Antonino A.
