Update the r8a73a4 code to allow using other
timers than Arch timer for clock event

Add clock event support for CMT1 timer channel 0
to the r8a73a4 SoC code. The CMT is used together
with a 32KHz clock in this case.

Add clock event support for CMT0 timer channel 0
to the r8a7790 SoC code. On most ARM mach-shmobile
the CMT is hooked up to a 32KHz clock but on r8a7790
a 31.7KHz clock is instead used.

The r8a7790 MSTP bits should be kept sorted in the same way
as on other mach-shmobile SoCs. Move the HSCIF and thermal
bits to clean up the current state.

r8a73a4 SoCs have numerous I2C controllers, of which 9 are compatible with
the i2c-sh_mobile.c driver. This patch adds clock definitions for them.

The Z2 clock on r8a73a4 is used to clock the 4 Cortex A7 cores on the SoC.
Add a definition for this clock to later use it from the arm_big_little
CPUFreq driver.

clk_set_rate() should only be called with exact rates, returned by
clk_round_rate(). However, it is still good to verify, that the value,
passed to clock's .set_rate() method is at least valid. This patch adds
such a check for the Z-clock on r8a73a4.

This patch adds support for the Z-clock on r8a73a4 SoCs, which is driving
the Cortex A15 core, and a "cpufreq-cpu0" platform device. Adding an
"operating-points" property to the CPU0 DT node and a regulator, this
patch allows platforms to use the generic cpufreq-cpu0 driver to use
SoC's DVFS capabilities.

To reconfigure clocks, controlled by FRQCRA and FRQCRB, a kick bit has to
be set and to make sure the setting has taken effect, it has to be read
back repeatedly until it is cleared by the hardware. This patch adds the
waiting part, that was missing until now.

There is still a board specific C file used for enabling
legacy SH clocks. This file will be removed after we have
moved over to common clocks.

Update the EMEV2 struct map_desc to exclude the SMU
and also include the ->map_io() callback in the DT
version of EMEV2 board support.
The EMEV2 SMP code can these days perform ioremap()
early on without the SMU information in the io_desc[].
To correctly support SMP in case of DT-only board
support then the ->map_io() callback is needed.
