mediatek/mt8173: Add soc ARM Trusted Firmware support

We define a mechanism to pass board specific parameters to BL31. The
    idea is BL31 doesn't need to have the board revision knowledge, it
    only needs to process the board specific parameters to initialize and
    control specific hardware. In this way, we can support different boards
    with same BL31 binary.

[pg: add the code, but don't actually enable the support yet, because it
    relies on code that still needs to be merged to arm-trusted-firmware.]

BRANCH=none
    BUG=none
    TEST=booted on oak-rev2 and oak-rev3 boards, and confirmed they got
         different board arguments in ARM TF
