The cpufreq-dt-platdev driver supports creation of cpufreq-dt platform
device now, reuse that and remove similar code from platform code.
Note that the complete routine imx27_dt_init() is removed as
of_platform_populate(NULL, of_default_bus_match_table, NULL, NULL);
has same effect as a NULL .init_machine machine callback pointer.

Instead of __raw_*, define imx_* to *_relaxed and use those.
Using imx_* was requested by Arnd because *_relaxed tends to
indicate that the code was carefully reviewed to not require
any synchronisation and otherwise be safe, which isn't the
case here with the automatic conversion.
The conversion itself was done using the following spatch
(since that automatically adjusts the coding style unlike
a simple search&replace).

System restart mechanism has been changed with the introduction
of "kernel restart handler call chain support". The imx2 watchdog
based restart handler has been moved to the driver, and these
restart can be removed from the machine layer.
This patch cleans up the device tree version machine reset init with
mxc_arch_reset_init_dt and removes corresponding .restart handler,
for the .init_machine that can be handled by system default after
removing the mxc_arch_reset_init_dt, the .init_machine is also removed.

The naming convention of this driver was always under the scanner, people
complained that it should have a more generic name than cpu0, as it manages all
CPUs that are sharing clock lines.
Also, in future it will be modified to support any number of clusters with
separate clock/voltage lines.
Lets rename it to 'cpufreq_dt' from 'cpufreq_cpu0'.

Otherwise GCC will mark the .init.rodata section R/W, which causes
a compile error once we add other real R/O data.

The only code left in mm-imx5.c is to create static mapping. While all
IMX platform code are moved to use dynamic mapping, the file can just be
removed now.

These imx5 init_early[late] hooks are called only from mach-imx5x.c.
Let's move them into mach-imx5x.c.
While at it, replace the static mapping in imx51_ipu_mipi_setup() with
dynamic mapping. Also this function and imx_src_init() do not
necessarily to be called at .init_early hook, so move them into
.init_machine.
The mxc_iomux_v3_init() is dropped from imx51_init_early() in the
moving, since it's only needed by non-DT boot.

After i.MX51 supports DT only, tzic_init_irq() can figure out the
tzic_base on its own. Thus, it can directly be .init_irq hook, and
mx51[53]_init_irq() can be saved.

Since i.MX51 becomes DT only now, we can drop option MACH_IMX51_DT and
just use SOC_IMX51 instead. While at it, rename imx51-dt.c to
mach-imx51.c to align with the name schema of other IMX DT only
platforms.
