soc/intel/meteorlake: Remove the check for INFR
Remove the check to follow the new flow that commit 9c348a7b7ea3
("soc/intel/alderlake: Fix processor hang while plug unplug of
TBT device") introduced.
Processor hang is observed while hot plug unplug of TBT device. BIOS
should execute TBT PCIe RP RTD3 flow based on the value of
TBT_DMA_CFG_VS_CAP_9[30]. It should skip TBT PCIe RP RTD3 flow, if
BIT30 in TBT FW version is not set.
