ARM: shmobile: r8a7778: cleanup registration of i2c

i2c-rcar driver which doesn't need platform data at the time of
registration can be registerd on SoC.
And, registering these drivers in the SoC code can avoid
unwanted device numbering issue.
(ex. the i2c3 device number will be i2c.0 if i2c3 only registered)

ARM: shmobile: r8a73a4: safeguard against wrong clk_set_rate() uses

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.

ARM: shmobile: r8a73a4: implement CPU clock scaling for CPUFreq

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.
