nvmem: rmem: make ->reg_read() straight forward code
memory_read_from_buffer() is a weird choice; it: - is made for iteration with ppos a pointer. - does futile error checking in our case. - does NOT ensure we read exactly N bytes. Replace it by: 1. A check that (offset + bytes) lands inside the region and, 2. a plain memcpy().
