[U-Boot] [PATCH] kmp204x: set the ZL clk chips reset to power up only

[Valentin Longchamp]

There is the requirement on the chassis's backplane that when the clocks
are enabled, they should not disappear. Resetting theses chips at unit
reset also has the side effect that their clocks disappear.

To avoid this side effect, both the ZL chips are reset only in the event
of a power cycle.
