[PATCH 3/3] net: lan966x: make reset optional

[Michael Walle]

There is no dedicated reset for just the switch core. The reset which
is used up until now, is more of a global reset, resetting almost the
whole SoC and cause spurious errors by doing so. Make it possible to
handle the reset elsewhere and mark the reset as optional.
