net: hix5hd2_gmac: fix compatible strings name

The SoC hix5hd2 compatible string has the suffix "-gmac" and
we should not change its compatible string.
So we should name all the compatible string with the suffix "-gmac".
Creating a new name suffix "-gemac" is unnecessary.

We also add another SoC compatible string in dt binding documentation
and describe which generic version the SoC belongs to.

 Required properties:
 - compatible: should contain one of the following SoC strings:
-	* "hisilicon,hix5hd2-gemac"

-	* "hisilicon,hisi-gemac-v2"
+	* "hisilicon,hisi-gmac-v1"
+	* "hisilicon,hisi-gmac-v2"
+  The version v1 includes SoCs hix5hd2.
+  The version v2 includes SoCs hi3798cv200, hi3516a.
 - reg: specifies base physical address(s) and size of the device registers.
   The first region is the MAC register base and size.
   The second region is external interface control register.
