powerpc: fix 8xx and 82xx type-punning warnings with GCC 4.7
C99's strict aliasing rules are insane to use in low-level code such as a bootloader, but as Wolfgang has rejected -fno-strict-aliasing in the past, add a union so that 16-bit accesses can be performed. Compile-tested only. Signed-off-by: Scott Wood <scottwood@freescale.com> Acked-by: Wolfgang Denk <wd@denx.de>
