pinctrl: meson: fix pinconf bias disable
[ Upstream commit e39f9dd8206ad66992ac0e6218ef1ba746f2cce9 ]
If a bias is enabled on a pin of an Amlogic SoC, calling .pin_config_set()
with PIN_CONFIG_BIAS_DISABLE will not disable the bias. Instead it will
force a pull-down bias on the pin.
Instead of the pull type register bank, the driver should access the pull
enable register bank.
