imx8: power: Add PD device lookup interface to power domain uclass
Add power_domain_lookup_name interface to power domain uclass to find
a power domain device by its DTB node name, not using its associated
client device.
Through this interface, we can operate the power domain devices directly.
This is needed for non-DM drivers.
Modified from Ye's NXP downstream patch
only for legacy imx8 power domain driver, since we have not migrated
to use new power domain driver.
