Subject: [PATCH v2 0/7] soc: fsl: guts: cleanups and serial_number support

This series converts the guts driver from a platform driver to just an
core_initcall. The driver itself cannot (or rather should never) be
unloaded because others depends on detecting the current SoC revision
to apply chip errata. Other SoC drivers do it the same way. Overall I
got rid of all the global static variables.

The last patch finally adds unique id support to the guts driver. But
because the binding [1] for the security fuse processor is still pending,
it is marked as RFC.
