Abolish unused ucBoardRev variables

Abolish unused ucBoardRev variables

[David Gibson]

asm-powerpc/processor.h declares, and arch/ppc/platforms/prep_setup.c
defines variables ucBoardRev, ucBoardRevMaj and ucBoardRevMin which
are used nowhere in the current kernel (neither in arch/ppc nor
arch/powerpc).  This patch removes them.
