dt-bindings: misc: Convert IDT 89HPESx to DT schema

Convert the IDT 89HPESx device binding to DT schema format.

"onsemi,24c64" was not a documented compatible string, so update the
example to "atmel,24c64". It's not clear what's in use here as no
upstream dts files have the eeprom child node.

-EEPROM / CSR SMBus-slave interface of IDT 89HPESx devices
-
-Required properties:
-  - compatible : should be "<manufacturer>,<type>"
-		 Basically there is only one manufacturer: idt, but some
-		 compatible devices may be produced in future. Following devices
-		 are supported: 89hpes8nt2, 89hpes12nt3, 89hpes24nt6ag2,
-		 89hpes32nt8ag2, 89hpes32nt8bg2, 89hpes12nt12g2, 89hpes16nt16g2,
-		 89hpes24nt24g2, 89hpes32nt24ag2, 89hpes32nt24bg2;
-		 89hpes12n3, 89hpes12n3a, 89hpes24n3, 89hpes24n3a;
-		 89hpes32h8, 89hpes32h8g2, 89hpes48h12, 89hpes48h12g2,
-		 89hpes48h12ag2, 89hpes16h16, 89hpes22h16, 89hpes22h16g2,
-		 89hpes34h16, 89hpes34h16g2, 89hpes64h16, 89hpes64h16g2,
-		 89hpes64h16ag2;
-		 89hpes12t3g2, 89hpes24t3g2, 89hpes16t4, 89hpes4t4g2,
-		 89hpes10t4g2, 89hpes16t4g2, 89hpes16t4ag2, 89hpes5t5,
-		 89hpes6t5, 89hpes8t5, 89hpes8t5a, 89hpes24t6, 89hpes6t6g2,
-		 89hpes24t6g2, 89hpes16t7, 89hpes32t8, 89hpes32t8g2,
-		 89hpes48t12, 89hpes48t12g2.
-  - reg :	 I2C address of the IDT 89HPESx device.
-
-Optionally there can be EEPROM-compatible subnode:
-  - compatible:  There are five EEPROM devices supported: 24c32, 24c64, 24c128,
-		 24c256 and 24c512 differed by size.
-  - reg:         Custom address of EEPROM device (If not specified IDT 89HPESx
-    (optional)	 device will try to communicate with EEPROM sited by default
-		 address - 0x50)
-  - read-only :	 Parameterless property disables writes to the EEPROM
-    (optional)
-
-Example:
-	idt@60 {
-		compatible = "idt,89hpes32nt8ag2";
-		reg = <0x74>;
-		#address-cells = <1>;
-		#size-cells = <0>;
-
-		eeprom@50 {
-			compatible = "onsemi,24c64";
-			reg = <0x50>;
-			read-only;
-		};
-	};
