ADIN1300 supports software control over pin polarity for both LED_0 and
LINK_ST pins.
Add new properties to set pin polarity:
- adi,led-polarity:
LED_0 is used as hardware configuration signal during reset.
Depending on external voltage on the line default value is either
active-high (0) or active-low (1).
- adi,link-st-polarity:
LINK_ST is always active-high (0) after reset.
