ADIN1300/1200 support software control over pin polarity for both LED_0
and LINK_ST pins.

LED_0 polarity can be supported in led framework with led_polarity_set
callback in  a future patch-set.
LINK_ST is a fixed-function output not suitable for led framework.

Add bindings for specifying the polarity of LINK_ST pin in device-tree,
and implement in adin phy driver.
