mmc: via-sdmmc: Simplify initialisation of pci_device_id array

Instead of assigning the pci_device_id members using a list (which is
hard to read as you need to look at the order of the members in that
struct in parallel) use the PCI_VDEVICE() convenience macro to compact
the initialisation while improving readability.

Also drop trailing zeros that the compiler will care about then.

The change doesn't introduce binary changes to the compiled driver,
verified on both ARCH=x86 and ARCH=arm64.
