Contribution description
If SDHC runs off the CPU clock and we wait for the transfer to complete, we can not enter IDLE mode as that will stop the CPU clock.
Add a new mode that acts as a no-op where we just spin the CPU.
Testing procedure
No change in behavior or power consumption as IDLE is unblocked by default.
