imx6[ull]guf: Add kernel-module-imx6-spreadspectrum

Add the kernel-module-imx6-spreadspectrum that adds the spread spectrum feature to reduce EMI.

The dynamic user interface is the /proc/mx6_spreadspectrum but the normal interface is the device tree interface.

For more details on the module use the source (Luke).

imx6-spreadspectrum: Update and fix possible bufferoverflow.

Update to use the recent proc_ops. Fix possible buffer overflow: The bounds were checked by the complaining compiler, so I do not deserve credit.

Harmonize the recipes and Makefiles for imx6-spreadspectrum and rtc-pcf8563-guf.

The imx6-spreadspectrum is still not installed by default for imx6(ull) devices.

imx6-spreadspectrum: Initial commit for imx6-spreadspectrum

Adds the G&F iMX6 spread spectrum module. Pulled version c8281e689bd64f65f35ada11801b6ac4f05ca4b7 from the G&F rocko port.

Does not build yet due to kernel 4.1 to 5.10 incompatibilities.
