[PATCH v2 5/5] pinctrl: qcom: ipq4019: support all pin functions

Currently, IPQ4019 pinctrl driver supports only a very limited number of
pin functions and is not fully DT compatible with Linux pinctrl nodes.
IPQ40xx SoC-s sometimes use different pin function numbers for the same
function depending on the pin number, so for example I2C0 on GPIO58 uses
function number 3 while on GPIO59 it uses function number 2.
So, in order to make the driver compatible with upstream DTS to avoid the
need to patch the pinctrl nodes in U-Boot and support all of the missing
pin functions lets rework the driver based on upstream Linux IPQ4019
pinctrl driver and the pending SM8150 U-Boot pinctrl driver which also uses
different function numbers pased on the exact pin number.
