mfd: sec-core: Allow building as module 



The main MFD driver for Samsung PMICs (S2MPSXX, S5M876X) used with
Exynos SoCs can be compiled and used as a module.  The dependent clock,
regulator and RTC drivers already can be built as a module.

Building entire set of drivers as modules might require using initial
ramdisk and can make booting process longer (due to probe deferrals).
However adding such option is useful for testing and for multi-platform
configurations.

This also add required module authors to sec-irq.c file based on recent
main contributors.

	  Have in mind that important core drivers (like regulators) depend

	  on this driver so building this as a module might require proper

	  initial ramdisk or might not boot up as well in certain scenarios.
