[PATCH 17/21] hw/scsi/vmw_pvscsi: Remove PVSCSI_COMPAT_DISABLE_PCIE_BIT definition

[Philippe Mathieu-Daudé]

PVSCSI_COMPAT_DISABLE_PCIE_BIT was only used by the
hw_compat_2_5[] array, via the 'x-disable-pcie=on' property.
We removed all machines using that array, lets remove all the
code around PVSCSI_COMPAT_DISABLE_PCIE_BIT.
