FUJITA Tomonori 32cb384038 rust: dma: fix broken intra-doc links ...

The `pci` module is conditional on CONFIG_PCI. When it's disabled, the
intra-doc link to `pci::Device` causes rustdoc warnings:

warning: unresolved link to `::kernel::pci::Device`
  --> rust/kernel/dma.rs:30:70
   |
30 | /// where the underlying bus is DMA capable, such as [`pci::Device`](::kernel::pci::Device) or
   |                                                                      ^^^^^^^^^^^^^^^^^^^^^ no item named `pci` in module `kernel`

Fix this by making the documentation conditional on CONFIG_PCI.
