[PATCH v3] bus: ts-nbus: drop unneeded dependency on OF_GPIO

[Bartosz Golaszewski]

OF_GPIO is selected automatically on all OF systems. Any symbols it
controls also provide stubs and are private to GPIOLIB anyway so there's
really no reason to select it explicitly.

Changes in v3:
- Send the bus patch separately so that it can be picked up for v7.2
- Link to v2: https://patch.msgid.link/20260316-gpio-of-kconfig-v2-0-de2f4b00a0e4@oss.qualcomm.com

Changes in v2:
- Make gpio-watchdog depend on OF && GPIOLIB
- Drop picked up patches
- Link to v1: https://patch.msgid.link/20260304-gpio-of-kconfig-v1-0-d597916e79e7@oss.qualcomm.com

Is the plan to hide it from the user eventually?

Yes, that's what I'm trying to do, but I need to remove all these
dependencies tree-wide first.
