Add mt6370 DisplayBias and VibLDO support.

Other than one small thing this looks nice and clean:

• enable_gpio = fwnode_gpiod_get_index(of_fwnode_handle(np), "enable", 0,

• 			     GPIOD_OUT_HIGH |
  

• 			     GPIOD_FLAGS_BIT_NONEXCLUSIVE,
  

• 			     desc->name);
  

• if (IS_ERR(enable_gpio)) {

• config->ena_gpiod = NULL;
  

• return 0;
  

• }

Please just use the OF APIs - due to ACPI's handling of power for devices the regulator API OF bindings can't be used sensibly on ACPI so it's better to explicitly work on DT only. This won't actually cause problems here but it's a bit clearer.
