Revert "arch: arm: dts: agilex5: Set SDIO_SEL GPIO pin as output"
Remove GPIO hog configuration for SDIO_SEL pin as it is now handled
through the voltage regulator framework for SD ultra high speed mode
support. The GPIO pin 3 on portb controller is used to control the
level shifter for SD card I/O voltage switching.
The regulator-based approach provides proper voltage switching control
for UHS-I modes (SDR50, SDR104) while maintaining compatibility with
the MMC subsystem's voltage switching protocols.
This reverts commit b0dbc9fcb7dfb7522be25ee205997be2fb5e1bdc.
