mei: vsc: Enhance IVSC chipset stability during warm reboot

During system shutdown, incorporate reset logic to ensure the IVSC
chipset remains in a valid state. This adjustment guarantees that
the IVSC chipset operates in a known state following a warm reboot.

Fixes: 566f5ca97680 ("mei: Add transport driver for IVSC device")
