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().
