device: Add fixed_mem_range_flags() and helpers 

Unlike fixed_mem_resource_kb() the arguments are not in KiB.
This allows coccinelle script to assign the base and size
without applying the KiB division or 10 bit right-shift.

Unlike with fixed_mem_resource_kb() the IORESOURCE_STORED flag is
passed in the flags parameter until some inconsistencies in the tree
get resolved.
