When prepare_message callbacks fail, the SPI core already reports which
controller the failure happened on. The corresponding code in the mem_ops
portion of the driver already reports the device a timeout occurred on,
so make the regular part of the driver do the same.

This series fixes some runtime PM related issues in the cadence-quadspi

Included is also a couple of related cleanups.
Commit 30dbc1c8d5 ("spi: cadence-qspi: defer runtime support on
socfpga if reset bit is enabled") fixed a warm reset issue on SoCFPGA by
disabling runtime PM on that platform.
Clean up the quirk implementation by never dropping the runtime PM usage
count on probe instead of sprinkling conditionals throughout the driver
which makes the code unnecessarily hard to read and maintain.

The driver is relying on the assumption that the invalid interrupt 0 can
be freed without any side effects, but that is not the case on
architectures like x86 where it would trigger a warning about freeing an
already free interrupt.
This should not cause any trouble on powerpc where this driver is used,
but make the code more portable (and obviously correct) by making sure
that the interrupts have been requested before freeing them.

Initial SoC Slider support

x86_energy_perf_policy accesses the SoC Slider via standard
user/kernel APIs to the processor_thermal_soc_slider driver.
Machines that support SoC Slider largely use it instead of EPP,
which may continue to exist in a diminished role, or vanish entirely.
Signed-off-by: Len Brown <len.brown@intel.com>
When processor_thermal_soc_slider is loaded, its slider
and offset modparams are visible. Check that the driver
actually registered the profile named "SoC Slider" before
reading or writing these modparams.
n.b. This utility allows writing the Slider and Offset modparams
even if the driver policy is not "balanced". Currently the
processor_thermal_soc_slider consults those modparams
only in "balanced" mode.
