esirisc: support eSi-RISC targets

Browse Source 
eSi-RISC is a highly configurable microprocessor architecture for
embedded systems provided by EnSilica. This patch adds support for
32-bit targets and also includes an internal flash driver and
uC/OS-III RTOS support. This is a non-traditional target and required
a number of additional changes to support non-linear register numbers
and the 'p' packet in RTOS support for proper integration into
EnSilica's GDB port.
