Subject: [PATCH 10/10] arm64: dts: ti: k3-am642-sk|evm: Drop bootargs, add aliases

Drop bootargs and add aliases based on base pinout of SK as per [1] and
evm per [2].

Indices chosen attempt to maintain some level of consistency with
existing aliases.

While at this, drop a extra EoL. While this patch could be split, it
seems trivial to add additional cleanup steps.
