[U-Boot] [RFC PATCH v1 0/2] edison: Enable ACPI

This RFC series based on discussion [1] to show how we may unleash the
powerfulness of ACPI on the board, which initially didn't support it,
via U-Boot.

The series is highly experimental, though I'm using it on daily basis
since my main work on ACPI pin control glue layer.

More information is available on [2].

Note, I dunno the split of DSL pieces is fully correct since we need to
understand the difference between SoC, platform, and board terms. Even
though some stuff here declared under 'tangier' folder it's related to
Intel Merrifield platform (like Wi-Fi chip connected to SDIO port of
Intel Tangier). Because of some restrictions of ACPI language /
interpreter I may not split some of those parts. Thus, it needs to be

P.S. It would be nice if someone who possess the board can check and
test this independently.
