phylib: rename reset-(post-)delay-us to reset-(de)assert-us

Browse Source 
As suggested by Rob Herring [1] rename the previously introduced
reset-{,post-}delay-us bindings to the clearer reset-{,de}assert-us

- reset-gpios: The GPIO phandle and specifier for the PHY reset signal.
- reset-delay-us: Delay after the reset was asserted in microseconds.
- reset-assert-us: Delay after the reset was asserted in microseconds.
If this property is missing the delay will be skipped.
- reset-post-delay-us: Delay after the reset was deasserted in microseconds.
- reset-deassert-us: Delay after the reset was deasserted in microseconds.
