All LXT PHYs implement the standard "power down" bit 11 of
BMCR, so this patch adds support using the generic
genphy_{suspend,resume} functions added by
commit 0f0ca340e57b ("phy: power management support").

LXT970 is left aside because all registers get cleared upon
"power down" exit.

 I'd be happy if you could also merge that into 4.19
