Add Elkhart Lake support

Browse Source 
Elkhart Lake has a chipset called Mule Creek Canyon which is quite
compatible with 300 series chipsets. There are a few differences though,
e.g. different encoding for the SPI clock values for read and write in
the FLCOMP register. In addition Elkhart Lake has a new PCI device ID
for the SPI controller which is added, too.
