Hi Tony,

Convert to the SET_PM_RUNTIME_PM macro while defining the runtime PM
callbacks. This means the callbacks becomes available for both
CONFIG_PM_SLEEP and CONFIG_PM_RUNTIME, which is needed to handle the
combinations of these scenarios.

Use clk_disable_unprepare and clk_prepare_enable from the runtime PM
callbacks, to fully gate|ungate clocks. Potentially this will save more
power, depending on the clock tree for the current SOC.

Due to the available runtime PM callbacks, we are now able to put our
device into low power state at system suspend.
Earlier we could not accomplish this without trusting a power domain
for the device to take care of it. Now we are able to cope with
scenarios both with and without a power domain.
Use devm_* functions to simplify code and error handling.

Since the runtime PM state is expected to be active according to the
amba bus, we must align our behaviour while probing to it.
Moreover, this is needed to be able to have the driver fully functional
without depending on CONFIG_RUNTIME_PM.

Since the device is active while a successful probe has been completed,
the reference counting for the clock will be screwed up and never reach
zero.
The issue is resolved by implementing runtime PM callbacks and let them
handle the resources accordingly, including the clock.

For !CONFIG_PM_RUNTIME, the device were never put back into active

For CONFIG_PM_RUNTIME, we blindly trusted the device to be inactive
while we were about to handle it at suspend late, which is just too
optimistic.

At system suspend_late, runtime PM has been disabled by the PM core
