rtc: simplify devm_request_mem_region/devm_ioremap

Browse source 
Convert the composition of devm_request_mem_region and devm_ioremap to a
single call to devm_ioremap_resource.  The associated call to
platform_get_resource is also simplified and moved next to the new call
to devm_ioremap_resource.

This was done using a combination of the semantic patches
devm_ioremap_resource.cocci and devm_request_and_ioremap.cocci, found in
the scripts/coccinelle/api directory.

In rtc-lpc32xx.c and rtc-mv.c, the local variable size is no longer needed.

In rtc-ds1511.c the size field of the local structure is not useful any
more, and is deleted.
