bnxt_en: Retry PTP TX timestamp from FW for 1 second

Use a new default 1 second timeout value instead of the existing
1 msec value.  The driver will keep track of the remaining time
before timeout and will pass this value to bnxt_hwrm_port_ts_query().
The firmware supports timeout values up to 65535 usecs.  If the
timeout value passed to bnxt_hwrm_port_ts_query() is less than the
FW max value, we will use that value to precisely control the
specified timeout.  If it is larger than the FW max value, we will
use the FW max value and any additional retry to reach the desired
timeout will be done in the context of bnxt_ptp_ts_aux_eork().
