mfd: sec-core: Allow building as module

Browse Source 
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.

Support for the Samsung Electronics MFD series.
Support for the Samsung Electronics PMIC devices coming
usually along with Samsung Exynos SoC chipset.
This driver provides common support for accessing the device,
additional drivers must be enabled in order to use the functionality
of the device
To compile this driver as a module, choose M here: the
module will be called sec-core.
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.
