According to the datasheet, the operating clock for IIC0 is the HPP
(RT Peri) clock, not the SUB (Peri) clock. Both clocks run at the same
speed (50 Mhz).

This is consistent with IIC0 being located in the A4R PM domain, and
IIC1 in the A3SP PM domain.

In general Renesas hardware is not documented to the extent
where the relationship between IP blocks on different SoCs can be assumed
although they may appear to operate the same way. Furthermore the
documentation typically does not specify a version for individual
IP blocks. For these reasons a convention of using the SoC name in place
of a version and providing SoC-specific compat strings has been adopted.

Although not universally liked this convention is used in the bindings for
a number of drivers for Renesas hardware. The purpose of this patch is to
make use of the SoC-specific CMT compat string for the r8a7740 48-bit CMT
clock source.

There's no need to duplicate the interrupt-parent property in all DT
nodes as the kernel automatically walks parent nodes to find the
property. Specify it once in the root node only.

This is likely a copy-and-paste error from the
ARM GIC documentation, that has already been fixed.

address-cells should have been set to 0, as with the size
cells. As having those properties set to 0 is the
same thing as not specifying them, drop them completely.

We need three steps to prepare for the new Armadillo reference DT board code:
 - Split the device list into r8a7740_early_devices used by the old platform
   data setup (board-armadillo.c) and r8a7740_devices_dt used by both
   setup variants.
 - Introduce new r8a7740_init_delay() to be more flexible about calling
   shmobile_setup_delay().
 - For the generic r8a7740 support, we switch to device tree setup for
   the GIC, the irqpin devices and the I2C controllers.

This is slightly similar to commit 3b00f934
