There are large number of QSPI irqs that fire during boot/init and later
on every suspend/resume.
This could be made faster by doing DMA instead of PIO.
Below is comparison for number of interrupts raised in 2 acenarios...
Boot up and stabilise
Suspend/Resume
Sequence PIO DMA
=======================
Boot-up 69088 19284
S/R 5066 3430
The interrupts are less, yes, but does it save time or power?
We have not made measurements but the change is expected to improve
performance.
Testing revealed no regressions.
