payloads/external/LinuxBoot: Update x86_64 defconfig

* Add support for Linux 5.x
** Select PCI, which isn't the default anymore with 5.x
** Select google firmware driver, which wasn't build any more
* Add support for Intel LPSS uart
** Select MFD and MFD_INTEL_LPSS_PCI
** Increase console count to 32
* Add support for coreboot framebuffer
** Select FB_SIMPLE
* Add support for eMMC/SDHCI
** Select MMC_SDHCI_*
* Add support for u-root's localboot
** Select KEXEC_FILE_LOAD
** Select FIRMWARE_MEMMAP

Stats:
* Kernel size 1.9MiB
* U-root (core + systemboot) 4.6MiB

Tested on Intel APL Up² board:
* Fixes non working console on APL Up2 board and eMMC bootmedia shows up.
* Allows to boot GNU/Linux from eMMC using 'localboot'
