A separate Kconfig option HAVE_S3C2410_WATCHDOG for Samsung SoCs is not
really needed and the s3c24xx watchdog driver can depend on Samsung ARM
architectures instead.

The "HAVE_xxx_WATCHDOG" pattern of dependency is not popular and Samsung
platforms are here exceptions.  All others just depend on
CONFIG_ARCH_xxx.

This makes the code slightly smaller without any change in
functionality.

This is a combination of two trivial bugs:

- A platform should not be 'tristate', it should be a 'bool' symbol
  like the other platforms, if only for consistency, and to avoid
  surprises like this one.

- The clk Makefile does not traverse into the sprd subdirectory
  if the platform is disabled but the drivers are enabled for
  compile-testing.

Fixing either of the two would be sufficient to address the link failure,
but for correctness, both need to be changed.

CONFIG_COMMON_CLK_VERSATILE doesn't really do anything other than hiding
Arm Ltd reference platform clock drivers. It is both selected by the
platforms that need it and has a 'depends on' for those platforms. Let's
drop the selects and convert CONFIG_COMMON_CLK_VERSATILE into a
menuconfig entry. With this make CONFIG_ICST visible.

Move the 'select REGMAP_MMIO' to the drivers that require it (SP810 did
not).

This also has the side effect of enabling CONFIG_ICST for COMPILE_TEST
as it was not visible before.
