MLK-10774-31 lcd: add LCD_MONOCHROME
LCD_MONOCHROME is removed in commit f4469f50b0367820121ef2d313517d422ed70e1d.
Add related code back to support epdc.
In this patch, also include crm_regs.h in mx6slevk.c to make epdc code
be compiled ok.
COLOR_MASK is also added from commit a7de2953f51e70754190d3516167d58d27d17219
