[POWERPC] 85xx/86xx: refactor RSTCR reset code
On the majority of 85xx & 86xx we have a register that's ability to assert HRESET_REQ to reset the board. We refactored that code so it can be shared between both platforms into fsl_soc.c and removed all the duplication in each platform directory. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
