Subject: [PATCH 5/9] dt-bindings: rtc: rtc-aspeed: move to trivial-rtc

The RTCs documented in this binding require a compatible, a reg
and a single interrupt, which make them suitable for a direct
conversion into trivial-rtc.

-ASPEED BMC RTC
-==============
-
-Required properties:
- - compatible: should be one of the following
-   * aspeed,ast2400-rtc for the ast2400
-   * aspeed,ast2500-rtc for the ast2500
-   * aspeed,ast2600-rtc for the ast2600
-
- - reg: physical base address of the controller and length of memory mapped
-   region
-
- - interrupts: The interrupt number
-
-Example:
-
-   rtc@...81000 {
-           compatible = "aspeed,ast2400-rtc";
-           reg = <0x1e781000 0x18>;
-           interrupts = <22>;
-           status = "disabled";
-   };
