Unfortunately no. We really have a big mess with those integrated chipsets
that have something like 15 PCI devices inside one component. We cannot call
all of them 'VX855'. or 'VX800', as that would clash. Naming things
'PCI_DEVICE_VIA_VX800_SDHCI' is also not really correct, since the same
block appearas in other integrated chipsets, too.

As for VIA's documentation, every block is called something like D13F3 (pci
device 13 function 3), which doesn't really sound all that much better than
just putting a 0x95d0 there.

To make things even furter complicated, some VIA Docs refer to the SDHCI
controller as 'SDIO controller' and the via-sdmmc as 'SD card controller'...
