[SRU][R:linux-raspi][PATCH v2 0/1] Add EDATEC IPC/EXP unified board overlay

[Yufeng Gao]

BugLink: https://bugs.launchpad.net/bugs/2160474

SRU Justification

[Impact]

When installed on EDATEC Pi CM5 devices, the IPC/EXP series industrial PC carrier boards
are not supported, resulting in lack of PCA9535 GPIO expander configuration.

[Fix]

Pull the fix from upstream Raspberry Pi tree (rpi-6.18.y branch):
  - 256d6b4bc3352 overlays: ed-ipc: Add EDATEC IPC/EXP unified board overlay

[Test Plan]

* Compile tested
* Boot tested
* No impacts to existing features found

Install the built packages, reboot the machine with correct config.txt and CAN MCP2515 and
RTC PCF8563T should work.

[Regression potential]

Relatively low, as only a Devicetree overlay from upstream is added.
