Tobias Klauser c105e86ace nios2: Remove ucontext.h from exported arch headers
Commit 92d5dd8cd6 ("nios2: update pt_regs") removed the nios2 specific
ucontext.h, replacing it with the version from asm-generic. Thus it's no
longer necessary to include ucontext.h in exported headers.

Ley Foon Tan 1000197d80 nios2: System calls handling
This patch adds support for system calls from userspaces. It uses the
asm-generic/unistd.h definitions with architecture spcific syscall.
The sys_call_table is just an array defined in a C file and it contains
pointers to the syscall functions.
