matroxfb: fix size of memcpy
hw->DACreg has a size of 80 bytes and MGADACbpp32 has 21. So when memcpy copies MGADACbpp32 to hw->DACreg it copies 80 bytes but only 21 bytes are valid. Signed-off-by: Sudip Mukherjee <sudip.mukherjee@codethink.co.uk> Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
