Hi,

This series adds ULP0 fast mode intended to reduce the suspend/resume
time in the detriment of power consumption (patch 1/3).
Along with this patch 2/3 adds code to avoid requesting a PM mode
not available on platforms not supporting it.
Patch 3/3 decrements a device_node refcount after its usage.

Thank you,
Claudiu Beznea
