dt-bindings: leds: Add 'active-high' property
Other than described in commit c94d1783136e ("dt-bindings: net: phy:
Make LED active-low property common") the absence of the 'active-low'
property means not to touch the polarity settings which are inherited
from reset defaults, the bootloader or bootstrap configuration. Hence,
in order to override a LED pin being active-high in case of the default,
bootloader or bootstrap setting being active-low an additional property
'active-high' is required. Document that property and make it mutually
exclusive to the existing 'active-low' property.
