bnxt_en: Adjust timer based on ethtool stats-block-usecs settings.
The driver gathers statistics using 2 mechanisms. Some stats are DMA'ed
directly from hardware and others are polled from the driver's timer.
Currently, we only adjust the DMA frequency based on the ethtool
stats-block-usecs setting. This patch adjusts the driver's timer
frequency as well to make everything consistent.
