mei: vsc: Prevent timeout error with added delay post-firmware download
After completing the firmware download, the firmware requires some
time to become functional. This change introduces additional sleep
time before the first read operation to prevent a confusing timeout
error in vsc_tp_xfer().
Fixes: 566f5ca97680 ("mei: Add transport driver for IVSC device")
