This patch contains several minor cleanups related to compiler.h:
- Replace __always_unused() (which is a Linux-specific concept that
doesn't make sense without also having __maybe_unused(), and had zero
uses in the codebase) with __unused() which moves here from helpers.h
- Add __underscores__ to the names of all attributes in the compiler
attribute shorthand macros. This is necessary to make them work in
files where the same name was already used for an identifier (e.g.
cbfstool/cbfs.h's `unused` array of file types).
- Remove libpayload's own copy of compiler.h and make it directly pull
in the commonlib/bsd copy.

This patch ensures the IP initialization being done as part of MTL
bootblock code is able to complete the bootblock phase without any
visible hang.
The re-ordering in the MTL bootblock SoC programming is required to
ensure the SA early initialization is taking place prior to
performing any PCI Read/Write operation (like P2SB bar enabling for
IOE die etc.).
Additionally, Fast SPI init takes place prior to enabling ROM caching
etc.
