linux: Enable CONFIG_I2C_BRCMSTB for proper HDMI I2C support

This patch enables the CONFIG_I2C_BRCMSTB option in vc4graphics.cfg to ensure proper support for the `brcm,bcm2711-hdmi-i2c` device node. Without this configuration, the I2C bus associated with HDMI on Broadcom BCM2711-based systems may fail to probe, causing issues with HDMI communication and display initialization. Additionally, this resolves potential deferred probe issues observed in the kernel logs, ensuring the correct initialization of the HDMI I2C bus. Signed-off-by: Garrett Brown <[email protected]>
