fsi/fsi-master-gpio: Reduce turnaround clocks
FSI_GPIO_PRIME_SLAVE_CLOCKS is the number of clocks if the
"idle" phase between the end of a response and the beginning
of the next one. It corresponds to tSendDelay in the FSI
specification.
The default value in the slave is 16 clocks. 100 is way overkill
and significantly reduces the driver performance.
This changes it to 20 (which gives the HW a bit of margin still
just in case).
