mb/intel/kblrvp: Do not use Legacy mode for UART #2
All KBLRVP variants select the `INTEL_LPSS_UART_FOR_CONSOLE` Kconfig option and set `UART_FOR_CONSOLE` to `2`, so that UART #2 is used as coreboot console. However, the LPSS console driver requires the LPSS UART to be memory-mapped (and not I/O-mapped, like Super I/O UARTs). KBLRVP variant RVP8 uses `PchSerialIoLegacyUart` for UART #2, which makes FSP-S configure UART #2 in legacy, I/O-mapped mode. This most likely results in the UART console not working after FSP-S has run. This change updates RVP8 to use `PchSerialIoSkipInit` for UART #2, like the other KBLRVP variants do.
