i.MX7ULP support 3 levels idle as below:
1. patial stop mode 3;
2. patial stop mode 2;
3. patial stop mode 1.

PSTOP1 - Partial Stop with system and bus clock disabled
PSTOP2 - Partial Stop with system clock disabled and bus clock enabled
PSTOP3 - Partial Stop with system clock enabled and bus clock enabled

For PSTOP 1/2 mode, as the system and bus clock will be disabled, the
devices working inprogress may not be able to work anymore, driver needs
to use pm_qos API to prevent system enter those modes.

Will you consider in the future to move the driver to a DT based
description and to the cpuidle-arm driver ?
