arm: dts: k3-am654: Add a specific IDK overlay for SR1.0 

The AM654 IDK daughter card supports few additional peripherals
like MCAN and 4 ICSSG Ethernet ports. The ICSSG IP is different
between the two AM65x Silicon Revisions SR1.0 and SR2.0, and so
warrants a separate overlay file when using on top of a AM654
base board populated with a SR1.0 silicon.

Add a new k3-am654-idk-sr1.dts overlay file, which includes the
k3-am654-idk.dts overlay file. The built overlays are identical
for now, but will diverge after ICSSG Ethernet support is added.

This fixes the following warning currently seen in A53 SPL on
AM65x EVMs with SR1.0 after the board logic is fixed up to pick
the separate overlay for kernel in commit ba961d78ac16 ("board:
ti: am65x: Use different overlay for IDK with SR1.0 EVM")
  "cannot find image node 'k3-am654-idk-sr1': -1"
