soc/intel/apollolake: Add utility functions for global reset
Apollolake defines Global Reset where Host, TXE and PMC are reset.
During boot we may need to trigger a global reset as part of platform
initialization (or for error handling). Add functions to trigger
global reset, enable/disable it and lock global reset bit.
