This change is fixing the parsing of PHY LE CODED which is
represented with value 0x03 instead of 0x04 in LE PHY Update
Complete event.

> HCI Event: LE Meta Event (0x3e) plen 6
	  LE PHY Update Complete (0x0c)
		Status: Success (0x00)
		Handle: 0
		TX PHY: LE Coded (0x03)
		RX PHY: LE Coded (0x03)
