Tokunori Ikegami c925d688e4 mtd: cfi_cmdset_0002: Use chip_ready() for write on S29GL064N 
commit 0a8e98305f upstream.

Since commit dfeae1073583("mtd: cfi_cmdset_0002: Change write buffer to
check correct value") buffered writes fail on S29GL064N. This is
because, on S29GL064N, reads return 0xFF at the end of DQ polling for
write completion, where as, chip_good() check expects actual data
written to the last location to be returned post DQ polling completion.
Fix is to revert to using chip_good() for S29GL064N which only checks
for DQ lines to settle down to determine write completion.
