powerpc: fix build when CONFIG_BOOKE_WDT is enabled
Commit ae3a197e (Disintegrate asm/system.h for PowerPC) broke build of
assembly files when CONFIG_BOOKE_WDT is enabled as follows:
AS arch/powerpc/lib/string.o
/home/baruch/git/stable/arch/powerpc/include/asm/reg_booke.h: Assembler messages:
/home/baruch/git/stable/arch/powerpc/include/asm/reg_booke.h:19: Error: Unrecognized opcode: `extern'
/home/baruch/git/stable/arch/powerpc/include/asm/reg_booke.h:20: Error: Unrecognized opcode: `extern'
Since setup_32.c is the only user of the booke_wdt configuration variables, move
the declarations there.
