pinctrl: tree-wide probe devices during core_initcall ...

Since commit 37e6bee7e5 ("gpiolib: Add support for GPIO "hog" nodes")
barebox can handle hog-gpios. To work correctly the pinctrl driver
must be initialised first. Reorder all pinctrl drivers so they will be
called first.

find drivers/pinctrl/ -type f -name *.c \
	-exec sed -i 's/\bpostcore_initcall\b/core_initcall/' "{}" +;

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.
