Watson Zeng fe24ae7ca4 [bsp][synopsys] add basic new embarc bsp support 
* the initial support of synopsys designware ARC processor
  using embARC_BSP, all synopsys ARC-based boards are
  supported:
  -ARC Software Development Platform
  -ARC EM Starter Kit
  -ARC EM Software Development Platform
  -ARC HS Development Kit
  -ARC IoT Development Kit

* The embARC BSP is a new generation embARC software development
  package.  ​It is designed to be the inter-layer between hardware and
  operating system. ​ BSP could hide the difference of hardware/boards,
  provide a unified interface to upper-layer.

* the initial support of synopsys MWDT toolchain.
  The DesignWare® ARC® MetaWare Development Toolkit builds upon
  a 25-year legacy of industry-leading compiler and debugger products.
  It is a complete solution that contains all the components needed to
  support the development, debugging and tuning of embedded applications
  for the DesignWare ARC processors.

* for detailed board information, pls go embarc.org.

MIPS common code was highly duplicated, This commit
is a attempt to clean-up and refine these code.

The context and exception handle flow is mostly identical
with Linux, but a notable difference is that when FPU enabled,
we save FP registers in stackframe unconditionally.

[libcpu][C28x] Fix bugs of old c28x interrupt api which can not save and restore int status 
In C28x DSP, interrupt status are stored in ST1 register. Both INTM and DBGM is used for masking interrupt, while the latter one is used in real-time debug mode. The origin function rudely enable and disable the interrupt without considering the recent interrupt status, which not only may cause  problem in some situation but also is not in conformity with rt-thread design specifications. The new api will fix this bug.

qz721 61f2a71511 Rename 'platform.h' in 'imx6ul' and 'qemu-vexpress-a9' BSPs. 
This filename conflicts with the 'mbedtls' package. They are renamed
in the name of the corresponding chips and included in 'board.h'.
Files that rely on this file should include 'board.h' instead.
