realtek: eth: rtl960x: increase ring sizes and buf size

Browse Source 
The GMAC on RTL9607C can handle ring sizes of up to 4096. Fix the comment
to now say 4096 is max instead of 256 and change the rx/tx ring sizes to 1024
and 2048 respectively to follow the vendor's defaults from their nic driver.

Also change the RX_BUF_SIZE to 1600 as the mentioned nic driver has the
SKB_BUF_SIZE set to 1600.
