tacoma: Remove CP0 reset
This is wired as to do nothing on normal Witherspoons, so the code to do
so has questionable utility.
On Tacoma systems, the Witherspoon motherboard is reworked to allow the
BMC to control the reset. The control is provided as part of the FSI
driver in the kernel, so it should be removed from the userspace power
control tool.
Fixing this should resolve this message when doing poweron:
power_control.exe[250]: ERROR PowerControl: GPIO open error (gpio=BMC_CP0_RESET_N,rc=2)
The GPIO device can't be opened as the kernel has control of it.
(From meta-ibm rev: 5ef58e42bd2c27605cd952bf590b2879759425d8)
