cache: Introduce external cache controller system support The cache API currently shipped in Zephyr is assuming that the cache controller is always on-core thus managed at the arch level. This is not always the case because many SoCs rely on external cache controllers as a peripheral external to the core (for example PL310 cache controller and the L2Cxxx family). In some cases you also want a single driver to control a whole set of cache controllers. Rework the cache code introducing support for external cache controllers.

cache: Fix cache API calling from userspace When a cache API function is called from userspace, this results on ARM64 in an OOPS (bad syscall error). This is due to at least two different factors: - the location of the cache handlers is preventing the linker to actually find the handlers - specifically for ARM64 and ARC some cache handling functions are not implemented (when userspace is not used the compiler simply optimizes out these calls) Fix the problem by: - moving the userspace cache handlers to a their logical and proper location (in the drivers directory) - adding the missing handlers for ARM64 and ARC Signed-off-by: Carlo Caione <ccaione@baylibre.com>
