soc/mediatek: Fill coreboot table with PCIe info 

In order to pass PCIe base address to payloads, implement pcie_fill_lb()
to fill coreboot table with PCIe info.

TEST=Build pass and boot up to kernel successfully via SSD on Dojo
board, here is the SSD information in boot log:
 == NVME IDENTIFY CONTROLLER DATA ==
    PCI VID   : 0x15b7
    PCI SSVID : 0x15b7
    SN        : 21517J440114
    MN        : WDC PC SN530 SDBPTPZ-256G-1006

    AERL      : 0x7
    SQES      : 0x66
    CQES      : 0x44
    NN        : 0x1
