[PATCH] spi: spi-mpc52xx.c: Init bus_num to 0 as this driver only supports one bus

[Stefan Roese <sr-ynQEQJNshbs@public.gmane.org>]

By setting bus_num to 0 the resulting device is named "spi0". Otherwise
the name was "spi32766" (dynamic numbering) which was a bit confusing.

Using 0 is correct as this driver (and the MPC5200 SPI controller) only
supports one SPI bus.
