Martin Åberg 07160fa153 arch: Add SPARC processor architecture 
SPARC is an open and royalty free processor architecture.

This commit provides SPARC architecture support to Zephyr. It is
compatible with the SPARC V8 specification and the SPARC ABI and is
independent of processor implementation.

Functionality specific to SPRAC processor implementations should
go in soc/sparc. One example is the LEON3 SOC which is part of this
patch set.

The architecture port is fully SPARC ABI compatible, including trap
handlers and interrupt context.

Number of implemented register windows can be configured.

Some SPARC V8 processors borrow the CASA (compare-and-swap) atomic
instructions from SPARC V9. An option has been defined in the
architecture port to forward the corresponding code-generation option
to the compiler.

Stack size related config options have been defined in sparc/Kconfig
to match the SPARC ABI.
