drivers/uio/uio_pruss.c: use gen_pool_dma_alloc() to allocate sram memory
Since gen_pool_dma_alloc() is introduced, we implement it to simplify code. Signed-off-by: Nicolin Chen <b42378@freescale.com> Cc: "Hans J. Koch" <hjk@hansjkoch.de> Cc: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
