[PATCH v2] arm64: dts: mediatek: mt6359: use proper compatible for rtc

[Louis-Alexis Eyraud]

The MT6359 PMIC include file uses directly "mediatek,mt6358-rtc"
compatible string for the rtc subnode, but not its own compatible
string.
Now that the "mediatek,mt6359-rtc" compatible is properly declared in
the dt-bindings, use it with "mediatek,mt6358-rtc" as fallback.

Several Mediatek and Radxa boards, based on MT8370, MT8390 or MT8395
SoC, integrate the MT6365 PMIC, that is a MT6359P variant:
 - Mediatek Genio 1200-EVK
 - Mediatek Genio 700-EVK
 - Mediatek Genio 510-EVK
 - Radxa NIO-12L
It is compatible with the MT6359 PMIC.

But both MT6365 PMIC support and compatibility were never expressed in
the dt-bindings and there is no MT6365 include file as well.
So, since these board support was introduced, their devicetrees use the
mt6359 include file to enable this PMIC support. 

The goal of this series is to clean this support by adding the missing
compatible strings for this MFD main and subdevices in the dt-bindings,
and add a include for MT6365 definitions to replace the MT6359 include
in these board devicetrees and for future ones (like Genio 520/720
EVKs).

The series is based on linux-next tree (tag: next-20260630) and has
been tested on Mediatek Genio 510, 700 and 1200-EVK boards.
