[ Upstream commit 1ab3030193d25878b3b1409060e1e0a879800c95 ]
During driver initialization the driver sends a reset to the device and
waits for the firmware to signal that it is ready to continue.
Commit d2f372ba0914 ("mlxsw: pci: Increase PCI SW reset timeout")
increased the timeout to 13 seconds due to longer PHY calibration in
Spectrum-2 compared to Spectrum-1.
Recently it became apparent that this timeout is too short and therefore
this patch increases it again to a safer limit that will be reduced in
the future.
Fixes: c3ab435466d5 ("mlxsw: spectrum: Extend to support Spectrum-2 ASIC")
Fixes: d2f372ba0914 ("mlxsw: pci: Increase PCI SW reset timeout")
