powerpc/8xx: Fix do_mtspr_cpu6() build on older compilers
GCC < 4.9 is unable to build this, saying:
arch/powerpc/mm/8xx_mmu.c:139:2: error: memory input 1 is not directly addressable
Change the one-element array into a simple variable to avoid this.
Fixes: 1458dd951f7c ("powerpc/8xx: Handle CPU6 ERRATA directly in mtspr() macro")
