arm: dts: imx8mp-toradex-smarc-dev-u-boot: add missing properties to PMICtoradex_u-boot-2024.07_smarc-imx8mp-bringup
During `power_init_board()`, the `pmic_get()` function was failing due
to missing properties in the device tree, resulting in the following
error:
"i2c_mxc i2c@30a20000: i2c bus 0 at 0x30a20000, fail to request scl/sda gpio"
This commit adds the required properties:
- gpio5 and pinctrl_i2c1_gpio -> sda and scl gpios
- gpio1 -> pmic interrupt pin
After the change, `pmic_get()` doesn't fail, and the PMIC initializes
correctly, enabling LDO4 and I2C level translator (CONFIG2) in pre-RAM
bootstage.
Upstream-Status: Pending
Fixes: 368fd87e2a30 ("arm: dts: imx8mp-toradex-smarc: sync with DT with Linux")
