Add Microchip MEC17xx family SPI master controllers and flash files. SPI implements public interface wrapper for QMSPI and GPSPI. MEC17xx family uses QMSPI for loading EC firmware. GPSPI is for general use (sensor). BRANCH=none BUG= TEST=Review only. Change-Id: I23001e254dd437caa0917949f4dd2eb903f1adb1 Signed-off-by: Scott Worley <scott.worley@microchip.corp-partner.google.com>
