dt-bindings: pinctrl: mt8186: Add and use drive-strength-microamp 



Commit e5fabbe4 ("pinctrl: mediatek: paris: Support generic
PIN_CONFIG_DRIVE_STRENGTH_UA") added support for using
drive-strength-microamp instead of mediatek,drive-strength-adv.

Similarly to the mt8192 and mt8195, there's no user of property
'mediatek,drive-strength-adv', hence removing it is safe.

              Describe the specific driving setup property.

              For I2C pins, the existing generic driving setup can only support

              2/4/6/8/10/12/14/16mA driving. But in specific driving setup, they

              can support 0.125/0.25/0.5/1mA adjustment. If we enable specific

              driving setup, the existing generic setup will be disabled.

              The specific driving setup is controlled by E1E0EN.

              When E1=0/E0=0, the strength is 0.125mA.

              When E1=0/E0=1, the strength is 0.25mA.

              When E1=1/E0=0, the strength is 0.5mA.

              When E1=1/E0=1, the strength is 1mA.

              EN is used to enable or disable the specific driving setup.

              Valid arguments are described as below:

              0: (E1, E0, EN) = (0, 0, 0)

              1: (E1, E0, EN) = (0, 0, 1)

              2: (E1, E0, EN) = (0, 1, 0)

              3: (E1, E0, EN) = (0, 1, 1)

              4: (E1, E0, EN) = (1, 0, 0)

              5: (E1, E0, EN) = (1, 0, 1)

              6: (E1, E0, EN) = (1, 1, 0)

              7: (E1, E0, EN) = (1, 1, 1)

              So the valid arguments are from 0 to 7.
