soc/intel/skylake: Enable LPC IO Decoding on PCR According to the PCH BIOS Spec (Doc#549921/Rev-2.3.4), section 2.5.1.6, it is a requirement to program the same value programmed in LPC "PCI offset 82h" into "PCR[DMI]+2774h" to fully enable the Lpc IO enable decoding which is missing in current source. Without above changes, Skylake Saddlebrook platform with a SIO does not boot.

soc/intel: Drop `dev` parameter from soc_get_gen_io_dec_range() This change drops the parameter `struct device *dev` from the function `soc_get_gen_io_dec_range()`. This function uses the parameter dev to get a pointer to config structure for extracting the decode ranges configured by mainboard in device tree. However, there is no separate chip driver for the LPC device which means that the SoC code can use `config_of_soc()` to get to SoC chip config instead of using the LPC device. This change is being done in preparation to clean up the device tree/chip config access in early stages that allows for optimizing the inclusion of device tree elements in the early stages.

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?
