virtio-devices: Rename VIRTIO_F_IOMMU_PLATFORM

Browse Source 
Rename the transport feature bit constant from
VIRTIO_F_IOMMU_PLATFORM to VIRTIO_F_ACCESS_PLATFORM across
the entire virtio-devices crate.

The virtio specification as of v1.1 carries bit 33 as
VIRTIO_F_ACCESS_PLATFORM. The Linux kernel UAPI header
<linux/virtio_config.h> carries VIRTIO_F_IOMMU_PLATFORM
only as a backward-compatible alias.

This is a pure rename with no functional or behavioral
change.
