[ARM] 3912/1: Make PXA270 advertise HWCAP_IWMMXT capability
ARM patch 3756/1 added HWCAP_IWMMXT. This patch adds support
for broadcasting that info via /proc/cpuinfo and sets it for
the CPU features of the PXA270.
I've booted 19rc3 on a pxa270 and confirmed that the /proc/cpuinfo
shows "iwmmxt" in the Features.
