[PATCH 2/4] xtensa: fix error with dma_supported

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

commit 11bd9421d0ad ("dma-mapping: cosolidate dma_mapping_error") has
removed dma_mapping_error() from arch specific file to
asm-generic/dma-mapping-common.h but it was not removed from xtensa
architecture and as a result we were getting error like:
error: redefinition of 'dma_mapping_error'
while building with allmodconfig.
