There's no need to try to be cute with the include file locations in the
Makefile, so just specify exactly where the files are.
Bonus is this fixes the problem of building with O= as well as trying to
just build the subdirectory alone.

This patch allows the user to modify the TPC PLL clock relaxation value
on-the-fly in order to reduce power consumption.
To enable this, the patch removes the protection from the specific
register that controls this behavior.

This patch adds the basic part of Goya's H/W initialization. It adds code
that initializes Goya's internal CPU, various registers that are related to
internal routing, scrambling, workarounds for H/W bugs, etc.
It also initializes Goya's security scheme that prevents the user from
abusing Goya to steal data from the host, crash the host, change
Goya's F/W, etc.
