[PATCH master] ARM: dts: imx93-frdm: allow dummy supplies for the PMIC regulators

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

From: Ahmad Fatoum <a.fatoum@barebox.org>

Since commit 63277454ed06 ("ARM: boards: i.MX93: use kernel dts"), the
FRDM uses the upstream DT, which supplies the eMMC from the PMIC.

No defconfig enables a driver for the PCA9451A PMIC, so with deep probe
both regulator lookups would now fail with -EPROBE_DEFER.

Let's allow dummy supplies for the PMIC regulators as we already do for
the TQMa93xx.

Fixes: 63277454ed06 ("ARM: boards: i.MX93: use kernel dts")
Assisted-by: Claude:opus-5.5
