Subject: [PATCH v3] arm64: dts: zii-ultra: update MDIO speed and preamble

Update MDIO configuration with zii-ultra device to fully utilize
MDIO endpoint capabilities. Device supports 12.5MHz clock and
doesn't require MDIO preamble.

Signed-off-by: Chris Healy <[email protected]>

v3:
- make "status = okay" the last property
v2:
- Fix subject line to reference zii-ultra:
- Get rid of "=<1>;" from suppress-preamble lines
