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
driver that implements ChipCommon specific interface communication.
Enabling this symbol will let bcma recognize serial flash and register
it as platform device.
