[PATCH] OMAP: DMA: Use some define rather than a hexadecimal constant for LCD register

[Janusz Krzysztofik]

The patch corrects the issue introduced with my previous patch:
	"OMAP: DMA: Fix omapfb/lcdc on OMAP1510 broken when PM set"
as pointed out by OMAP subsystem maintainer.

Hi,

I'd really like to have the first one get in as a fix in the -rc series,
that's why I decided to correct the issue in a follow up.

Thanks,
Janusz
