MAINTAINERS: Extend Samsung SoC entry with S3C/S5P drivers

Some of the drivers for S3C and S5P families of Samsung SoCs go in
through Samsung SoC tree.  Extend the entry so proper maintainers would
be displayed in such cases, most notably the cpufreq drivers.  This does
not change the work-flow for other drivers which have sub-maintainers
(like Samsung clocks).
