[Adrian Bunk <bunk@kernel.org>]

Commit 8b798c4d16b762d15f4055597ff8d87f73b35552 causes compile errors 
like the following for several system types:

 error: 'PSC0_BASE_ADDR' undeclared here (not in a function)

 warning: no previous prototype for 'au1xxx_platform_init'
make[2]: *** [arch/mips/au1000/common/platform.o] Error 1

<--  snip  -->

One or more #include <asm/mach-au1x00/au1xxx_psc.h>'s at the right 
places seem to be the correct solution, but I don't understand the mips 
subarch setup good enough for knowing where to place them.
