MIPS: Refactor GIC clocksource code.
Reorganize some of the GIC clocksource driver code. Below is a list of
the various changes.
* No longer select CSRC_GIC by default for Malta platform.
* Limit choice for either the GIC or R4K clocksource, not both.
* Change location in Makefile.
* Created new 'gic_read_count' function in common 'irq-gic.c' file.
* Change 'git_hpt_read' function in 'csrc-gic.c' to use new function.
* Surround GIC specific code in Malta platform code with #ifdef's.
* Only initialize the GIC clocksource if it was selected. Original
code called it unconditionally if a GIC was found.
