908df725ad arch: use up_current_regs/up_set_current_regs replace CURRENT_REGS
reason:
1 On different architectures, we can utilize more optimized strategies
  to implement up_current_regs/up_set_current_regs.
eg. use interrupt registersor percpu registers.

d212e15a43 This commit adds basic architectural support for the OpenRISK mor1kx architecture. The initial commit was verified on a Qemu simulation but is otherwise untested.
Squashed commit of the following:

Author: Gregory Nutt <gnutt@nuttx.org>
    Update README.
    configs/or1k:  Should include header file file where exported functin is prototyped.
    arch/or1k/src:  Eliminate some warnings.
    arch/or1k:  Complete review
    Fix some recently introduced build issues
    configs/or1k/nsh:  Convert to proper, compressed defconfig file.
    Another README update.
    Update README
    configs/or1k:  Updates from initial review.
    Update README.
