[PATCH v2 3/7] dt-bindings: rtc: mt6397: merge to MFD mediatek,mt6397 DT schema

[Macpaul Lin <macpaul.lin@xxxxxxxxxxxx>]

Convert rtc-mt6397.txt be compatible with the DT schema.
Since this is a simple RTC device node, merge it into parent
mediatek,mt6397.yaml. Subsequently, remove rtc-mt6397.txt with a
separate patch.

Changes for v1 and v2:
 - This is the first version of converting rtc-mt6397.txt.
   This is because converting rtc-mt6397 together
   with mfd/mediatek,mt6397.yaml, so we've create a patch set
   instead of submitting single patch for each subdevice.
 - This patch has been made base on linux-next/master git repo.

-Device-Tree bindings for MediaTek PMIC based RTC
-
-MediaTek PMIC based RTC is an independent function of MediaTek PMIC that works
-as a type of multi-function device (MFD). The RTC can be configured and set up
-with PMIC wrapper bus which is a common resource shared with the other
-functions found on the same PMIC.
-
-For MediaTek PMIC MFD bindings, see:
-../mfd/mt6397.txt
-
-For MediaTek PMIC wrapper bus bindings, see:
-../soc/mediatek/pwrap.txt
-
-Required properties:
-- compatible: Should be one of follows
-       "mediatek,mt6323-rtc": for MT6323 PMIC
-       "mediatek,mt6358-rtc": for MT6358 PMIC
-       "mediatek,mt6366-rtc", "mediatek,mt6358-rtc": for MT6366 PMIC
-       "mediatek,mt6397-rtc": for MT6397 PMIC
-
-Example:
-
-       pmic {
-               compatible = "mediatek,mt6323";
-
-               ...
-
-               rtc {
-                       compatible = "mediatek,mt6323-rtc";
