MLK-11318-5: video: mxsfb: porting mxsfb driver to imx_4.1.y branch
Porting mxsfb driver to imx_4.1.y branch.
Signed-off-by: Fancy Fang <chen.fang@freescale.com>
Also added dependency to FB_MXC_SYNC_PANEL to fix imx_v6_v7_deconfig
build during 4.14 rebase. This was initially a small part of
commit fe2905013882 ("MLK-15048-2: video: Add proper config dependencies")
