Add support for SPMI PMIC GPIO subtypes GPIO_LV_VIN2 and
GPIO_MV_VIN3.
GPIO_LV_VIN2 GPIOs support two input reference voltages: VIN0 and
VIN1. These are typically connected to 1.8 V and 1.2 V supplies
respectively.
GPIO_MV_VIN3 GPIOs support three input reference voltages: VIN0,
VIN1, and VIN2. These are typically connected to Vph, 1.8 V, and
1.2 V supplies respectively.

Commit b6d09f7807 ("pinctrl: nomadik: Drop U8540/9540 support") removes
the DB8540 pin controller driver and its config PINCTRL_DB8540.
There is some code left-over in the generic nomadik pinctrl driver, i.e.,
drivers/pinctrl/nomadik/pinctrl-nomadik.{ch}, that is still around for the
removed DB8540 pin controller driver.
Remove this remaining dead code.
This issue was discovered with ./scripts/checkkconfigsymbols.py.
