[ Upstream commit d2f372ba0914e5722ac28e15f2ed2db61bcf0e44 ]
Spectrum-2 PHY layer introduces a calibration period which is a part of the Spectrum-2 firmware boot process. Hence increase the SW timeout waiting for the firmware to come out of boot. This does not increase system boot time in cases where the firmware PHY calibration process is done quickly.
