The patch corrects the issue introduced with one of my earlier patches:
	OMAP: DMA: Fix omapfb/lcdc on OMAP1510 broken when PM set[1]
as pointed out by OMAP subsystem maintainer.

Applies on top of my prevoius patch:
  OMAP: DMA: move LCD DMA related code from plat-omap to mach-omap1[2]

Tested on Amstrad Delta
Compile tested with omap_generic_2420_defconfig
