All Samsung platforms include different types of clock including
fixed-rate, mux, divider and gate clock types. There are typically
hundreds of such clocks on each of the Samsung platforms. To enable
Samsung platforms to register these clocks using the common clock
framework, a bunch of utility functions are introduced here which
simplify the clock registration process. The clocks are usually
statically instantiated and registered with common clock framework.

Add entries to __clksrc_of_table so that Exynos MCT controller is
discoverable using call to clocksource_of_init. With this change,
it would be appropriate to rename the function 'exynos4_timer_init'
as 'mct_init' since it aptly describes this function. Additionally,
the 'init_time' callback of all machine descriptors for exynos
platforms that were previously set to 'exynos4_timer_init' are now
set to either 'mct_init' or 'clocksource_of_init'.

Instead of using soc_is_xxx macro at more than one place in
the MCT controller driver to decide the MCT interrpt number
to be setup, populate a table of known MCT global and local
timer interrupts and use the values in table to setup the MCT
interrupts.

This also helps in adding device tree support for MCT controller
driver by allowing the driver to retrieve interrupt numbers from
device tree and populating them into this table, thereby supporting
both legacy and dt functionality to co-exist.

All the MCT register read/writes use a fixed remapped address
S5P_VA_SYSTIMER.  With device tree support for MCT controller,
it is possible to remove the static remap of the MCT controller
address space and do the remap during the initialization of the
MCT controller with the physical address obtained from the device
tree.

So in preparation of adding device tree support for MCT controller,
add a new register base address variable that will hold the remapped
MCT controller base address and convert all MCT register read/writes
to use this new variable as the base address instead of the fixed
S5P_VA_SYSTIMER.

While at it, the MCT register offset and bit mask definitions are
moved into the MCT controller driver file since there are no other
consumers of these definitions.
