net: systemport: Add support for SYSTEMPORT Lite
Add supporf for the SYSTEMPORT Lite Ethernet controller, this piece of hardware
is largely based on the full-blown SYSTEMPORT and differs in the following:
- no full-blown UniMAC, instead we have the MagicPacket matching from UniMAC at
same offset, and a GMII Interface Block (GIB) for the MAC-level stuff, since
we are always interfaced to an Ethernet switch which is fully Ethernet compliant
shortcuts could be made
- 16 transmit queues, whose interrupts are moved into the first Level-2 interrupt
controller bank
- slight TDMA offset change (a register was inserted after TDMA_STATUS, *sigh*)
- 256 RX descriptors (512 words) and 256 TX descriptors (not visible)
As a consequence of these two things, update the code paths accordingly to
differentiate the full-blown from the light version.
