[PATCH v2 00/17] x86: coral: Add support for Cr50

[Simon Glass]

This series adds a driver for the Cr50 security chip and enables it on
coral. This supports the 'tpm' command.

In order to make this work a few other changes are included:
- Additional UCLASS_IRQ operations to support requesting and reading
  interrupts, using the device tree
- A driver for ACPI general-purpose events

There are also a few small clean-ups to the recently landed Apollo Lake
support.

This series relies on this patch:

Changes in v2:
- Add new patch to allow iterating devices without uclass_get()
- Add new patch to find a device by drvdata
- Add new patch to change syscon to use helper function
- Add new patch to change tegra driver to use helper function
- Move intel-clock.h inclusion to the correct patch
- Move 'success' comment into this patch
- Update to use the new DM helper function
- Move 'success' comment into previous patch
- Move intel-clock.h inclusion to the correct patch
- Significant rewrite of cr50 init procedure
- Support use of interrupts
- Update the commit message
- Add new patches to handle requesting interrupts and interrupt state
