Revert "tacoma: Remove CP0 reset"
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.
