[PATCH 2/2] arm64: dts: renesas: rzg2ul-smarc: Add /omit-if-no-ref/ to pinmux

[Prabhakar]

From: Lad Prabhakar <prabhakar.mahadev-lad.rj@xxxxxxxxxxxxxx>

In preparation to re-use the RZ/G2UL SMARC SoM and carrier DTS/I with the
RZ/Five add /omit-if-no-ref/ keyword to pinmux entries as the support for
RZ/Five SMARC EVK will be gradually added.

Once we have full blown support for RZ/Five SMARC EVK we can get rid of
the /omit-if-no-ref/ keyword.

Signed-off-by: Lad Prabhakar <prabhakar.mahadev-lad.rj@xxxxxxxxxxxxxx>
