[flashrom-gerrit] Change in flashrom[master]: ft2232_spi.c: Pack read cmd and nCS in one ftdi_write_data() call

[Simon Buhrow (Code Review)]

Hello build bot (Jenkins),

I'd like you to reexamine a change. Please visit

https://review.coreboot.org/c/flashrom/+/40748

ft2232_spi.c: Pack read cmd and nCS in one ftdi_write_data() call

Every ftdi_write_data() call is quite time consuming as the ftdi-chip takes 2-3ms to respond.
As the comment already says: Minimize USB transfers by packing as many commands as possible together.

As I cannot see any reason to put read cmd and deassertion of nCS into separated ftdi calls,
I packed them together to save programming time.
