Marek Behún c677fb1e31 phy: Move PHY_INTERFACE_MODE_NA to the beginning of the enum definition
Move PHY_INTERFACE_MODE_NA to the beginning of the enum definition to
make it have zero value. This makes it possible (although not
encouraged) to test for invalid/nonexistent interface mode with !val
instead of val == PHY_INTERFACE_MODE_NA.

The comment near the definition says "Must be last", because when the
constant was introduced in commit 5f184715ec ("Create PHY Lib for
U-Boot"), it was used as the maximum value when interating over the
constants. But this is no longer true - we use PHY_INTERFACE_MODE_MAX
for that now, and so we can move it.
