This adds some code based on code from the Broadcom GPL tar to fix the
reboot problems on BCM4705/BCM4785. I tried rebooting my device for ~10
times and have never seen a problem. This reverts the changes in the
previous commit and adds the real fix as suggested by Rafał.
Setting bit 22 in Reg 22, sel 4 puts the BIU (Bus Interface Unit) into
async mode.
The previous commit was 316cad5c1d4daee998cd1f83ccdb437f6f20d45c [MIPS:
BCM47XX: make reboot more relaiable]
