Subject: [PATCH 22/41] ARM: omap1: move plat/dma.c to mach/omap-dma.c

From: Arnd Bergmann <arnd@...db.de>

Most of the interface functions in plat/dma.c are only used from the
USB driver, which is practically OMAP1 specific, except for compile
testing.

The omap_get_plat_info(), omap_request_dma() and omap_free_dma()
functions are never called on omap2 because of runtime checks.
