[S] Change in flashrom[master]: ichspi.c: plumb flashctx though hwseq xfer helper

ichspi.c: plumb flashctx though hwseq xfer helper

Change is a NOP to prepare ichspi to remove hwseq_data being
a global symbol. This allows for the helper functions to derive
their data from the driver data context.
