[PATCH AUTOSEL 6.18-5.10] rtc: aspeed: add AST2700 compatible

[Sasha Levin]

From: Tommy Huang <tommy_huang@xxxxxxxxxxxxxx>

[ Upstream commit 3319cfeeb8c4047026f84df045c438f7bbd338a6 ]

Add support for matching the RTC controller on ASPEED AST2700 SoCs.

The AST2700 RTC controller is compatible with the existing ASPEED
RTC driver implementation.

LLM Generated explanations, may be completely bogus:

The background searches finished and match what the earlier analysis
used.

The `b4 dig` lookup on the real commit (`3319cfeeb8c40`) found the lore
thread and confirmed this is patch 2/2 of the AST2700 RTC series, with
`5e7f746bc106a` as the companion DT-binding patch.

The stable-branch history search shows 6.18.y already has substantial
AST2700/G7 bring-up (gpio, mfd, irqchip, reset, mailbox, clock
bindings), but not the RTC compatible or `ast2700-rtc` binding yet.

Verdict unchanged: **YES** for backport to this 6.18.y tree, ideally
together with the binding patch.
