This reverts commit 5ef58e42bd2c27605cd952bf590b2879759425d8.
There is a unknown issue with Tacoma hardware in which the CP0 reset
needs to happen within the power_control.exe. The theory is it is timing
related (i.e. the CP0 reset needs to occur extremely close to the power
being turned on). Given that Tacoma is a development system, time has not
been allotted to getting to the bottom of this.
It works fine on some systems, but fails catastrophically on others with
an assortment of power fault errors.
Due to this issue, we can not utilize the new kernel mechanism for
controlling CP0 on Tacomas.

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.

The metadata common to all IBM systems is confusingly split between
meta-ibm and meta-witherspoon. Move everything to meta-ibm.
The meta-ibm README is re-written to more accurately reflect the scope
of the layer.
Allow the configuration samples (bblayers.conf.sample,
local.conf.sample) to be sourced from either meta-ibm or
meta-witherspoon until such a time that any workflows and tooling have
had the opportunity to move to meta-ibm.
