accel/ivpu: Remove D3hot delay for Meteorlake
VPU on MTL has hardware optimizations and does not require 10ms
D0 - D3hot transition delay imposed by PCI specification (PCIe
r6.0, sec 5.9.) .
The delay removal is traditionally done by adding PCI ID to
quirk_remove_d3hot_delay() in drivers/pci/quirks.c . But since
we do not need that optimization before driver probe and we
can better specify in the ivpu driver on what (future) hardware
use the optimization, we do not use quirk_remove_d3hot_delay()
for that.
