[PATCH 05/19] staging: brcm80211: remove MIPS specific 'sync' instruction in fullmac

[Arend van Spriel]

From: Roland Vossen <rvossen at broadcom.com>

This instruction was required for the bcm4716/bcm4322, but since the
fullmac driver only supports bcm4329, it could be removed. After that,
the R_REG macro's were identical and thus were reduced to just 1 R_REG
macro.
