MFP4: Changes to hopefully make the new power code work better
o Rather than just try to turn off EXCA_INTR_RESET, set the entire register
to 0. This is slightly faster, and a better hammer.
o Move attempted clearing of the output enable (EXCA_PWRCTL_OE) back to
after we turn off the power. Modify it to write 0 so that we don't get
Bad Vcc messages on TI bridges (untested, but ru@ sent me a similar patch)
while at the same time avoiding interrupt storms on Ricoh bridges (tested
by me on my Sony).
# Many of my observations of 'breakage' for this patch are due to some bug
# in the load/unload of cbb.ko unlreated to this change. I'll be investigating
# and fixing that bug in the fullness of time.
