[PATCH v2] MIPS: Add ifdefs to IP22/IP32's Platform files

[PATCH v2] MIPS: Add ifdefs to IP22/IP32's Platform files

[Joshua Kinard]

From: Joshua Kinard <kumba@gentoo.org>

Prevent IP22/IP32's Platform directives from mixing into builds of
other MIPS platforms.  The IP27 Platform file wraps its directives in
an ifdef block, but the IP22 and IP32 Platform files do not.  This can
lead to the possibility of directives for IP22 or IP32 getting mixed
into the builds of other MIPS platforms.
