drivers: eth_mcux: By default use 1 buffer each for hardware RX/TX
It was reported, and confirmed by multiple parties that default
CONFIG_ETH_MCUX_RX_BUFFERS=2 under some packet load leads to
1s and increasing packet processing delay and eventual deadlock.
No reports were about CONFIG_ETH_MCUX_TX_BUFFERS=2, but be on safe
side and just set that to the minimal value as the current default,
to allow us to have good conservative base to test various networking
stack issues.
Fixes: #3132
