bnxt_en: Optimize doorbell write operations for newer chips.
Older chips require the doorbells to be written twice, but newer chips
do not. Add a new common function bnxt_db_write() to write all
doorbells appropriately depending on the chip. Eliminating the extra
doorbell on newer chips has a significant performance improvement
on pktgen.
