soc/intel/apollolake: Initialize GPEs in bootblock

Initialize the GPEs from mainboard config in bootblock, so they
can be used in verstage to query latched interrupt status.

I still left it called in ramstage just to be sure that the
configuration was not overwritten in FSP stages.

Tested by reading and reporting GPE status in a loop in verstage
and manually triggering an interrupt on EC console.
