Subject: [PATCH net-next 1/2] net: phy: realtek: Add phy ids for RTL8226-CG/RTL8226B-CG

Realtek single-port 2.5Gbps Ethernet PHY ids as below:
RTL8226-CG: 0x001cc800(ES)/0x001cc838(MP)
RTL8226B-CG/RTL8221B-CG: 0x001cc840(ES)/0x001cc848(MP)
ES: engineer sample
MP: mass production

Since above PHYs are already in mass production stage,
mass production id should be added.
