@Function SGXResetSleep
@Description
Sleep for a short time to allow reset register writes to complete.
Required because no status registers are available to poll on.
@Input psDevInfo - SGX Device Info
@Input ui32PDUMPFlags - flags to control PDUMP output
@Input bPDump - Pdump the sleep
@Return Nothing
