ARM: dts: am43xx: add support for clkout1 clock
clkout1 clock node and its generation tree was missing. Add this based
on the data on TRM and PRCM functional spec.
commit 664ae1ab2536 ("ARM: dts: am43xx: add clkctrl nodes") effectively
reverted this commit 8010f13a40d3 ("ARM: dts: am43xx: add support for
clkout1 clock") which is needed for the ov2659 camera sensor clock
definition hence it is being re-applied here.
Note that because of the current dts node name dependency for mapping to
clock domain, we must still use "clkout1-*ck" naming instead of generic
"clock@" naming for the node. And because of this, it's probably best to
apply the dts node addition together along with the other clock changes.
Fixes: 664ae1ab2536 ("ARM: dts: am43xx: add clkctrl nodes")
