Allwinner Reduced Serial Bus support is only needed for sun[89]i
platforms. Having it built-in for multi-platform kernels leads to
a bigger kernel image, without any benefit for non sun[89]i systems.

The driver already exports the needed symbols and supports module
loading/unloading. Change the Kconfig symbol to tristate to allow
the user to build it as a module.

Hi Arnd,

Maxime requested we make the RSB driver and subsequent PMIC drivers
tristate. Please squash this patch into patch 2 of the RSB series
when you apply them.


Thanks
ChenYu
