Adds alias for SoC RTC so that it gets assigned rtc0. PMIC node is
assigned rtc1 so that PMIC RTC gets probed as rtc1. This makes it
consistent for testing rtcwake with other AM62 devices where rtc0
is SoC RTC.

Link to v1:
https://lore.kernel.org/all/20250212210604.745175-1-k-willis@ti.com/

Changes from v1 to v2:
- rebased on latest linux-next
- fix spelling mistake
- add test log

Tested on AM62A with rtcwake [1]. The wakeup source is 0x50 which 
indicates the SoC RTC is used to wakeup the system as detailed in the
TISCI documentation [2].

I have applied the following to branch ti-next on [1].
Thank you!

[1/1] arm64: dts: ti: k3-am62a7-sk: Add alias for RTC
      commit: 34887f2dab33b30de2730005681c796114fba351

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent up the chain during
the next merge window (or sooner if it is a relevant bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.
