DA8xx: move base address #define's to their proper place

Move DA8XX_MMCSD0_BASE, DA8XX_LCD_CNTRL_BASE,  and DA8XX_DDR2_CTL_BASE from
<mach/da8xx.h> to devices-da8xx.c as the latter file is the only place where
these macros are used.

While at it, restore sorting the base address macros by address value in
devices-da8xx.c...
