mb/google/volteer: Fix FPMCU pwr/rst gpio handling
1. No gpio control in bootblock
2. Power on and then deassert reset at the end of ramstage gpio
3. Disable power and assert reset when entering S5
On "reboot", the amount of time the power is disabled for is
equivalent to the amount of time between triggering #3 and wrapping
around to #2.
This change affects the following volteer variants that include an FPMCU:
1. Drobit
2. Eldrid
3. Elemi
4. Halvor
5. Malefor
6. Terrador
7. Trondo
8. Voema
9. Volteer2
10. Voxel
