soc/intel/skylake: Unify serial IRQ options

Browse Source 
We had two ways to configure the serial IRQ mode. One time in the
devicetree for FSP and one time through Kconfig for coreboot. We'll
use `enum serirq_mode` from soc/intel/common/ as a devicetree option
instead. As the default is `quiet mode` here and that is the most
common mode, this saves us a lot of lines.

In four cases kblrvp8, 11 and librem 13v2, 15v3, we had conflicting
settings in devicetree and Kconfig. We'll maintain the `continuous`
selection, although it might be that coreboot overrode this earlier
on the kblrvps.

Note: A lot of Google boards have serial IRQ enabled, while the pin
seems to be unconnected?
