fix: enable pinctrl for Raspberry Pi 5

dsseng · smira · commit 4f8efafbae29 · 2026-01-20T21:16:05.000+04:00
Without the pinmux driver some SoC peripherals, including debug UART and SD Host Controller are indefinitely stuck in deferred probing waiting for pinctrl, disabling essential functionality. Signed-off-by: Dmitrii Sharshakov <dmitry.sharshakov@siderolabs.com> (cherry picked from commit 30bc671)
