meta-ampere:u-boot: Add GPIO configuration for DVT boards

Mt.Jade DVT hardware requires some GPIO setting so that the board can
work well. This commit updates platform init function in u-boot to set
required GPIO pins.

Tested:
    1. Verify below GPIOs set as input in Linux:
     - S0_I2C9_ALERT_L (GPIOM4)
     - S1_I2C9_ALERT_L (GPIOM5)
     - GPIO_BMC_VGA_FRONT_PRES_L (GPIOQ7)
     - GPIO_BMC_EXT_HIGHTEMP_L
     - GPIO_S0_VRHOT_L
     - GPIO_S1_VRHOT_L
     - GPIO_BMC_PCA9554_INT_L
    2. verify below GPIOs set as output high in Linux
     - GPIO_BMC_I2C6_RESET_L
     - GPIO_BMC_JTAG_SRST_L
     - GPIO_BMC_VR_PMBUS_SEL_L
     - BMC_GPIOR2_EXT_HIGHTEMP_L
     - BMC_VGA_SEL
