net: fec: allow disable coalescing
[ Upstream commit b7ad21258f9e9a7f58b19595d5ceed2cde3bed68 ]
In the current implementation, IP coalescing is always enabled and
cannot be disabled.
As setting maximum frames to 0 or 1, or setting delay to zero implies
immediate delivery of single packets/IRQs, disable coalescing in
hardware in these cases.
This also guarantees that coalescing is never enabled with ICFT or ICTT
set to zero, a configuration that could lead to unpredictable behaviour
according to i.MX8MP reference manual.
