[U-Boot] [PATCH] am335x: cpsw: optimize cpsw_recv to increase network performance

[Vladimir Koutny <vladimir.koutny@streamunlimited.com>]

In 48ec5291, only TX path was optimized; this does the same also for RX
path. This results in huge increase of TFTP throughput on custom am3352
board (from 312KiB/s to 1.8MiB/s) and eliminates occasional transfer
timeouts.
