This series adds Intel Elkhart Lake PSE I/O driver which enumerates the
PCI parent device and splits two child I/O devices (GPIO and Timed I/O
which are available as a single PCI function through shared MMIO) to their
respective I/O drivers.

In spirit, it is a continuation of PSE TIO series[1] which received
objection from Greg for abusing platform device and has now been reworked
to use auxiliary device instead.

Currently TIO driver[2] falls under PPS subsystem supporting generator
functionality and will be coming up in a separate follow-up series for
its independent design changes as per below roadmap.

=> Extend TIO driver[2] to support PPS client functionality.
=> Develop a PPS common driver which hooks to both generator and client
   counterparts.
=> Develop an auxiliary glue driver for PPS common driver.
