soc/intel/skylake: Unify serial IRQ options
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?
