libpayload/pci: Add PCIe interfaces for MediaTek platform

Add PCIe configuration interfaces for MediaTek platform.

The register base address of PCIe hardware might be different when it's
a non-x86 platform, add 'pci_update_hw_base()' interface for users to
update its base address to access PCIe hardware correctly.

TEST=Build pass and boot up to kernel successfully via SSD on Dojo
board, here is the SSD information in boot log:
