MIPS: Delete Wind River ppmc eval board support.
This board has been EOL for many years now; lets not burden people doing build coverage and other tree wide work with working on essentially dead files. [ralf@linux-mips.org: Also remove arch/mips/include/asm/mach-wrppmc/war.h.] Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com> Cc: linux-mips@linux-mips.org Cc: Paul Gortmaker <paul.gortmaker@windriver.com> Patchwork: http://patchwork.linux-mips.org/patch/5503/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
