Intel Elkhart Lake Programmable Service Engine (PSE) includes two PCI
devices that expose two different capabilities of GPIO and Timed I/O
as a single PCI function through shared MMIO.

This series adds MFD driver for them and extends PPS generator driver
to support initial PSE TIO functionality.

v2: Use consistent naming with Intel drivers (Andy)
Add MFD dependency for child drivers (Andy)
Aesthetic adjustments (Andy)
Update tags
