soc/intel/apollolake: Add SMI and SCI support for ESPI

This patch adds the SMI bits for SMI_EN, SMI_STS and GPE
register in pm.h. The southbridge handler for espi smi is
also added. In gpe.h we add GPE0A_ESPI_SCI_STS which is
bit 20 in GPE register and enables the setting of the
ESPI_SCI STS bit to generate a wake event and/or an SCI/SMI.

TEST=  Boot to OS.
