Subject: [spmi-pmic-arb fixes and optimization patches V1 9/9] spmi: pmic-arb: increase SPMI transaction timeout delay

From: David Collins <collinsd@...eaurora.org>

Increase the SPMI transaction timeout delay from 100 us to
1000 us in order to account for the slower execution time
found on some simulator targets.
