lcd: Add CONFIG_LCD_ALIGNMENT to select frame buffer alignment
The normal alignment is PAGE_SIZE, but if this is defined, we can support other alignments. The motivation for this change is to make the display section-aligned on ARM so that we can easily turn off data caching for the frame buffer region without resorting to level 2 page tables.
