[PATCH 3/6] mips: introduce support for Platform definitions

Subject: [PATCH 3/6] mips: introduce support for Platform definitions
From: Sam Ravnborg <sam@ravnborg.org>
Date: Sun, 30 May 2010 16:03:25 +0200
Move platform specific definitions to the platfrom directories.

Each platform shall do the following:
1) include an entry in arch/mips/Kbuild.platforms
2) add relevant definitions to arch/mips/<platform>/Platform

This commits change ar7 to the new scheme as an example.

Introducing a platform speecific Platfrom file has following advantages:
1) decentralization of platfrom definitions
2) simplification af arch/mips/Makefile
3) force all platfrom to build with -Werror (done in arch/mips/Kbuild)
