Add driver for SIE Cronos control CPLD

Hello all,

This series adds a driver for the multi-function CPLD found on the Sony Interactive Entertainment Cronos x86 server platform. It provides a watchdog timer and an LED controller, both of which will depend on the MFD parent driver implemented in this series. Device tree bindings are also included.

Thanks,

Changes in v2:
- Change SIE to Sony (SIE's parent company) to be more consistent with how other subsidiaries are treated in the kernel.
- Drop SIE prefix addition patch
- Address review comments to dt bindings
- Add new properties to dt bindings
- Fix driver build failure detected by kernel test robot
