net: sun8i_emac: Fix DMA alignment issues with the rx / tx buffers

This fixes the following CACHE warnings when using sun8i_emac:

=> dhcp
BOOTP broadcast 1
BOOTP broadcast 2
CACHE: Misaligned operation at range [7bf594a87bf59628]
BOOTP broadcast 3
CACHE: Misaligned operation at range [7bf59c907bf59e10]
CACHE: Misaligned operation at range [7bf5a4787bf5a5f8]
DHCP client bound to address 10.42.43.80 (1009 ms)

Note this commit also changes the max rx size from 2024 to 2044,
matching what the kernel driver uses.
