Hi Anton,

At least freeze, restore and thaw need to be set in order for the driver

be reused since those functions don't touch the device's power state or
wakeup capability. Use the helper macros SET_SYSTEM_SLEEP_PM_OPS and
SET_NOIRQ_SYSTEM_SLEEP_PM_OPS for symmetry with similar drivers.
and why do we need hibernation in this device?

Hi!
I wanted to test whether hibernation is possible on our SoC, even though
it is not a common feature on embedded ARM systems. This is the only
mainline driver that I found that needed modification, for my
proof-of-concept anyway, and I couldn't see any harm in the change.
