meta-ampere: u-boot: Disable internal PD resistors for GPIOs

Configure SCU8C - Multi-function pin control 4 to disable internal pull
down resistors for GPIOJ, GPIOG/GPIOAB, GPIOD/GPIOY, GPIOC/GPIOS as
external resistors are already installed.

Tested: scan I2C4 and check devices on the bus are detected
