[coreboot] MinnowMax: Tentative patch for S3 suspend/resume support

[Mohan]

Hi,

This is a tentative patch for S3 suspend/resume support in MinnowMax Board.

It is based on the "src/soc/intel/baytrail/romstage/romstage.c" 
implementation.

Tested wakeup from Power Button and Magic packet using Debian Jessie RFS
and grub2.elf as coreboot payload.

S3 suspend/resume require Fast boot to be enabled.  (please correct me 
if i am mistaken)

Comments, suggestion, corrections are welcome.
I would like to get it added it, can anyone help me ?

Regards,
Mohan
