[PATCHv2 5/8] arm: ti: Remove ARCH= references from documentation

[Tom Rini]

When building U-Boot we select the architecture via Kconfig and not ARCH
being passed in via the environment or make cmdline.

Changes in v2:
- None

As an aside, these README files should be converted rST and moved to
doc/board/ and the MAINTAINERS file updated to include the new
documentation file too.  Thanks!
