The Telechips ARM architecture is being removed. This patch
deletes the arch/arm/mach-tcc8k/ folder.

There are two dividers used to derive bus clock from system clock:
system clock is divided by SCKDIV+1, then by BCKDIV+1. SCKDIV divider
has been ignored up to now, which is no problem as long as it is 0.
Take SCKDIV into account for bus clock calculation.

Remove double definition of ACLKUSBH, change parameter name in
root_clk_disable, as there is no reason to have a different name than
in root_clk_enable.
No functional change.

There is no reason why in case of PLL2 the configuration register
should be read twice, while for PLL0/1 using the value previously read
is used. Do the same for PLL2.

The calculation of the best divider value for a requested clock rate
always returned a value that was slightly too large. It was also not
protected against possible divisions by zero.
Request for very low, but non zero rates would cause the ACLK divisor
field to overflow. Catch this situation by using the maximum value.
The internal function aclk_set_rate() calculates the correct divider
value, but doesn't write it back to the register. Add the write back.

factorise some generic infrastructure to assist looking up struct clks
for the ARM & SH architecture.
as the code is identical at 99%
put the arch specific code for allocation as example in asm/clkdev.h

Add the system timer using clockevents with the internal TC32 timer.
This also adds a clocksource using the same timer.

This adds definitions and low-level functions to handle clocks in
TCC8xxx processors.
