The original commit that added support for the SYSTEMPORT Lite variant
halved the number of RX descriptors due to a confusion between the
number of descriptors and the number of descriptor words. There are 512
descriptor *words* which means 256 descriptors total.
Fixes: 44a4524c54af ("net: systemport: Add support for SYSTEMPORT Lite")
