Sascha Hauer 3bd69ad077 driver: replace dev_request_mem_region with dev_request_mem_resource 
dev_request_mem_region doesn't work properly one some SoCs on which
PTR_ERR() values clash with valid return values from dev_request_mem_region.
Replace them with dev_request_mem_resource where possible.

This patch has been generated with the following semantic patch:
