ARM: PL061: Checking register r/w accesses to reserved area
pl061.c emulates two GPIO devices, ARM PL061 and TI Stellaris, which
share the same read/write functions (pl061_read and pl061_write).
However PL061 and Stellaris have different GPIO register definitions
and pl061_read()/pl061_write() doesn't check it. This patch enforces
checking on offset, preventing R/W into the reserved memory area.
