ariesve: Some changes to gp4 voltage regulators to fix touchscreen voltage

These changes allow to prevent these errors when setting touchscreen voltage:
<3>[    0.063964] ldo10: requested voltage range [1800000, 1800000] does not fit within previously voted range: [2600000, 2600000]
<3>[    0.064086] oliver_tsp_ldo_on: vreg LDO2 set level failed (-22)

The touchscreen after getting this error uses the wrong voltage of
2600000 uV instead of 18000000 uV.

The regulator's core has been changed and the voltage range that doesn't
fit the previously set voltage range is not allowed, so we need to correct
the other occurrences where gp4 regulator has been registered.

ariesve: Moved the config_gpio_table method outside of the CONFIG_MSM_CAMERA block

This method is used by other drivers init methods
