Neither of these need to be exported, so just make them static.

All of the SH timers use a roughly identical structure for platform data,
which presently is broken out for each block. Consolidate all of these
definitions, as there is no reason for them to be broken out in the first
place.

This patch contains various fixes for 16-bit cmt hardware.
With this applied periodic clockevents work fine on sh7203.

This patch moves the SuperH timer setup code from time_init()
to late_time_init(). Good things about this change:
- interrupts: they are enabled at late_time_init()
- mm: regular kmalloc() can be used at late_time_init()
Together with moving to late_time_init() this patch changes
the sh_cmt driver to always allocate with kmalloc(). This
simplifies the code a bit and also fixes section mismatches.

This patch improves the sh_cmt clocksource handling.
Currently the counter value is ignored in the case of
overflow. With this patch the overflow flag is read
before and after reading the counter, removing any
counter value and overflow flag mismatch issues.

Add clocksource support to the sh_cmt driver. With this in
place we can do tickless with a single CMT channel.

Update the sh_cmt driver to make use of recent irq and clockevent changes:
- use remove_irq() together with setup_irq()
- remove mult workaround since WARN_ON() now has been moved

SuperH CMT clockevent driver.
Both 16-bit and 32-bit CMT versions are supported, but only 32-bit
is tested. This driver contains support for both clockevents and
clocksources, but no unregistration is supported at this point.
Works fine as clock source and/or event in periodic or oneshot mode.
Tested on sh7722 and sh7723, but should work with any cpu/architecture.
This version is lacking clocksource and early platform driver support
for now - this to minimize the amount of dependencies.
