A platform_driver does not need to set an owner, it will be populated by the
driver core.

linux/err.h isn't implicitly included by the current headers on all
platforms, resulting in compilation failures due to implicit
declarations of IS_ERR and PTR_ERR. Fix this by including linux/err.h.

The structure isn't used outside of its compilation unit. Make it
static.

Several functions and variables are use on SH_CPU4 or ARM only. Guard
their declaration with conditional compilation directives to avoid
warnings.

A bad merge resulted in a left-over free_irq() call. This patch removes it.

The driver core clears the driver data to NULL after device_release
or on probe failure. Thus, it is not needed to manually clear the
device driver data to NULL.

Macros, named like TEND or SAR lack a namespace and are too broadly named
for a global header. Besides, they aren't needed globally. Move them to
where they belong - into the driver. Some other macros aren't used at all,
remove them.

This facilitates DMAC DT support by eliminating the need in AUXDATA and
avoiding creating complex DT data. This also fits well with DMAC devices,
of which SoCs often have multiple identical copies and it is perfectly
valid to use a single configuration data set for all of them.
