Add sync at the end of flash_write_cmd for MPC86xx to ensure write command are really finished before reading data

According to Tolunay's first suggestion, this patch for cfi_flash driver fixed the flash operation error on MPC8641HPCN board. Since there is not such flash error reported on 85xx, 83xx platform and as Tolunay said, there is not a PowerPC macro to define, I just use CONFIG_MPC86xx for now. I also tested his second suggestion(adding udelay directly after reset command), but flash still failed to work.
Given that this is already looks to have been an issue on blackfin and now PPC (and probably some MIPS also), I would suggest it's better to define a macro in the CPU definition for your arch and blackfin and do a generic test like so:
#ifdef SYNC SYNC; #endif
Maybe you can come up with a more descriptive name than SYNC :-)
I had e-mailed Tolunay about this and he concurred.
