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.

Future additions will make the function too big to live as a static

console: drop f_caps and check the function pointer getc/putc instead ...

None of the driver make the difference between STDOUT and STDERR.
So we just need to check if putc or getc are filled in the console_device
