Convert CONFIG_SYS_NONCACHED_MEMORY to Kconfig
This converts the following to Kconfig:
CONFIG_SYS_NONCACHED_MEMORY
To do this we introduce CONFIG_SYS_HAS_NONCACHED_MEMORY as a bool to
gate if we are going to have noncached_... functions available and then
continue to use CONFIG_SYS_NONCACHED_MEMORY to store the size of said
cache. We make this new option depend on both the architectures which
implement support and the drivers which make use of it.
