[RFC v4 13/21] ath10k: different fw file names for usb and sdio

[Erik Stromdahl <erik.stromdahl@gmail.com>]

Since both SDIO and USB based chipsets will use different
firmware from the PCIe and AHB chipsets, the fw file name
must be different depending on bus type.

The new firmware names are:

For PCIe and AHB:
firmware-<api_version>.bin (same as before)

For SDIO:
firmware-sdio-<api_version>.bin

For USB:
firmware-usb-<api_version>.bin
