dt-bindings: pinctrl: mt8195: Add and use drive-strength-microamp

Browse Source 
commit 1b3ab63e56f0c30193b6787b083be4f4071b7fc6 upstream.

As was already done for MT8192 in commit b52e695324bb ("dt-bindings:
pinctrl: mt8192: Add drive-strength-microamp"), replace the custom
mediatek,drive-strength-adv property with the standardized pinconf
'drive-strength-microamp' one.

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

Fixes: 69c3d58dc187 ("dt-bindings: pinctrl: mt8195: Add mediatek,drive-strength-adv property")

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.
