bnxt_en: Reorganize the coalescing parameters.
The current IRQ coalescing logic is a little messy. The ethtool
parameters are mapped to hardware parameters in a way that is difficult
to understand. The first step is to better organize the parameters
by adding the new structure bnxt_coal. The structure is used by both
the RX and TX sets of coalescing parameters.
Adjust the default coal_ticks to 14 us and 28 us for RX and TX.
