udoo: Call gpio_request()
Calling gpio_request() prior to its usage is now mandatory. This fixes the following GPIO errors: U-Boot SPL 2022.01-rc3-00067-g7a5be871c0ec (Dec 18 2021 - 17:45:07 -0300) Trying to boot from MMC1 U-Boot 2022.01-rc3-00067-g7a5be871c0ec (Dec 18 2021 - 17:45:07 -0300) CPU: Freescale i.MX6Q rev1.2 at 792 MHz Reset cause: WDOG Model: Udoo i.MX6 Quad Board Board: Udoo Quad DRAM: 1 GiB MMC: FSL_SDHC: 2 Loading Environment from MMC...
