bwi: Remove unnecessary pcivar.h include
sdmmc: Capture lan_nid and expose sdmmc_cisptr
LAN NID contains the MAC address for networking adapters.
Device drivers may want to processor vendor specific tuple codes, so
expose sdmmc_cisptr to help this.
bwi(4): Add support for Nintendo Wii WLAN.
Adapt the bwi(4) driver to support SDIO attachment and driving TX/RX using
PIO instead of DMA since the latter is not supported on SDIO busses.
