bcma: allow enabling serial flash support on non-MIPS SoCs

So far we had only MIPS devices with serial flash connected to the SoC's ChipCommon. ARM devices got a separated SPI controller and weere using standard SPI drivers. This has changed with the wireless SoC BCM47189B0. It's ARM based but has serial flash attached just like older devices. This allows using existing driver with these devices.

+	  Some cheap devices have serial flash connected to the ChipCommon
+	  instead of independent SPI controller. It requires using a separated
