[Redfish] Enable PATCH for DHCPv4 properties in EthernetInterface schema

DHCPv4 were read-only properties, this code change make following
properties to be PATCHable:

- DHCPEnabled
- UseDNSServers
- UseDomainName
- UseNTPServers

Tested:
1. Check DHCPv4 properties value

	GET /redfish/v1/Managers/bmc/EthernetInterfaces/<ethID> HTTP/1.1
	Response:
	{
	    ......
	    "DHCPv4": {
	        "DHCPEnabled": true,
	        "UseDNSServers": true,
	        "UseDomainName": true,
	        "UseNTPServers": true
	    },
	    ......
	}

2. PATCH DHCPv4

	PATCH /redfish/v1/Managers/bmc/EthernetInterfaces/eth1 HTTP/1.1
	{
		"DHCPv4": {
			"DHCPEnabled":false,
	        	"UseDNSServers": false,
		        "UseDomainName": false,
		        "UseNTPServers": false
       		}
	}

3. Check whether DHCPv4 properties are set

        GET /redfish/v1/Managers/bmc/EthernetInterfaces/<ethID> HTTP/1.1
        Response:
        {
            ......
            "DHCPv4": {
                "DHCPEnabled": false,
                "UseDNSServers": false,
                "UseDomainName": false,
                "UseNTPServers": false
            },
            ......
        }
