Describe the bug

The cy8c95xx I2C GPIO expander support was broken in commit 4b30008 in #47841 PR. I can observe this issue when this I2C GPIO expander is connected to DW I2C controller (I haven't tried it with other I2C controllers due to the lack of such HW).

Currently we can see error messages during boot time:

E: cy8c95xx_port@1 init failed: -5
E: cy8c95xx_port@0 init failed: -5
*** Booting Zephyr OS build v3.3.0-rc1-5-gef9d5bbddfa5 ***

If we try to use GPIO's from this expander we'll get error that they are not ready.

To Reproduce
Steps to reproduce the behavior:
Build Zephyr from current main (ef9d5bb) for the hsdk board. It can be reproduced with both GNU toolchain (i.e: from Zephyr SDK 0.15.0) and MWDT (2022.09).

Environment (please complete the following information):

  • OS: Linux
  • Toolchain: Zephyr SDK 0.15.0
  • Commit SHA used for test: ef9d5bb
  • Bisected commit: 4b30008
