[PATCH 1/3] Platform/RaspberryPi/Acpitables: Enable Arasan hispeed mode


Jeremy Linton
 

The arasan caps registers are no longer being overridden by
the brcm iproc driver, so we should be assuring that the
"High Speed Support" bit 21 is set in the capability
register. This significantly improves the wifi perf
using linux.
