Several kukui boards share the same panel property and only compatible
is different. So compatible will be set in board dts for comparison

When suspending the driver, anx7625_power_standby() will be called to
turn off reset-gpios and enable-gpios. However, power supplies are not
disabled. To save power, the driver can get the power supply regulators
and turn off them in anx7625_power_standby().

Some SoCs, eg. mt8183, are using a pinconfig operation bias_set_combo.
The fallback path in mtk_pinconf_adv_pull_set() should also try this
operation.
