Add support for the SWTG018AS-A V2.0 8+1 unmanged switch

Browse Source 
The SWTG018AS-A V2.0 is an 8x2.5GBit/s port + 1 SFP+ port unmanged device
It is sold in an unbranded casing e.g. by Ampcom.
Hardware:
SoC: RTL8373N
Additional PHY: RTL8224
Flash: Puya P25D40SH (4MBit, slimmer, not standard SOP-8 package!)
LEDs: 1 Green + 1 Orange per Ethernet port (green designates 2.5GBit)
      1 Green LED for the SFP+ port

The photos already show a modified PCB: Unpopulated resistors R52 and R53
have been bridged in order to enable the serial console. The smaller flash
memory chip at U2 has been replaced with a Windbond 128MBit standard-sized
SOIC-8 chip in order to easily use SOIC clamps to flash the device. Also
the serial header has been populated.
