Memory layout is not fixed for noMMU xtensa configurations. Platforms
that need to use coherent DMA should implement platform_vaddr_* helpers
that check address type (cached/uncached) and convert addresses between
these types.

platform_restart implementatations do the same thing to reset CPU.
Don't duplicate that code, move it to a function and call it from
platform_restart.

Remove heading and trailing spaces, trim trailing lines, and wrap lines
that are longer than 80 characters.

platform_get/set_rtc_time() is not implemented by any of the supported
xtensa platforms. Remove the facility completely.
The initial seconds for xtime come from read_persistent_clock() which
returns just 0 in the generic implementation. Platforms that sport a
persistent clock can implement this function.
This is needed to implement the ccount as a clock source.

Move all header files for xtensa to arch/xtensa/include and platform and
variant header files to the appropriate arch/xtensa/platforms/ and
arch/xtensa/variants/ directories.
Moving the files gets also rid of all uses of symlinks in the Makefile.
This has been completed already for the majority of the architectures
and xtensa is one out of six missing.
