[PATCH v3 02/11] HID: Add BUS_SPI support and define HID_SPI_DEVICE macro

[Jingyuan Liang <jingyliang@chromium.org>]

From: Jarrett Schultz <jaschultz@microsoft.com>

If connecting a hid_device with bus field indicating BUS_SPI print out
"SPI" in the debug print.

Macro sets the bus field to BUS_SPI and uses arguments to set vendor
product fields.
