This outer cache allows to control active ways independently for
each CPU, so this function will be useful to set up active ways
for a specific CPU.

This invalidates entries in specified ways of the outer cache.

Move this option to Kconfig, renaming it into CONFIG_CACHE_UNIPHIER.
The new option name makes sense enough, and the same as Linux has.

Now, all of these macros are only used in cache-uniphier.c, so
there is no need to export them in a header file.

The System Cache (outer cache) is used not only as L2 cache,
but also as locked SRAM. The functions for turning on/off it
is necessary whether the L2 cache is enabled or not.

If CONFIG_UNIPHIER_L2CACHE_ON is undefined, the L2 cache is never
enabled, so there is no need for v7_outer_cache_disable(). The weak
stub avoids the compile error anyway.

The UniPhier outer cache (L2 cache on ARMv7 SoCs) can be used as
SRAM by locking ways.
These functions will be used to transfer the trampoline code for SMP
into the locked SRAM.

Unify the range/all operation routines into the common function,
uniphier_cache_maint_common(), and sync code with Linux a bit more.
This reduces the code duplication.

Sync register macros with Linux code. This will be helpful to
develop the counterpart of Linux.
