[PATCH 1/4] xtensa: fix error with dma_{alloc,free}_{attrs,coherent}

[Sudip Mukherjee <sudipm.mukherjee@gmail.com>]

commit 59b5f4726434 ("dma-mapping: consolidate dma_{alloc,free}_{attrs,coherent}")
has removed dma_{alloc,free}_{attrs,coherent} functions from arch
specific files to asm-generic/dma-mapping-common.h. But they were not
removed for xtensa architecture and as a result we are getting errors
like:
error: redefinition of 'dma_alloc_attrs'
error: redefinition of 'dma_free_attrs'
while building with allmodconfig.
