[ Upstream commit 5ecae9f8c705fae85fe4d2ed9f1b9cddf91e88e9 ]

For updating the IOC firmware's timestamp with system timestamp, the driver
issues the Mpi26IoUnitControlRequest message. While framing the
Mpi26IoUnitControlRequest, the driver should copy the lower 32 bits of the
current timestamp into IOCParameterValue field and the higher 32 bits into
Reserved7 field.
