regmap: change regmap_init_mem() to take ofnode instead udevice

Browse Source 
Currently, regmap_init_mem() takes a udevice. This requires the node
has already been associated with a device. It prevents syscon/regmap
from behaving like those in Linux.

Change the first argumenet to take a device node.
