arch-riscv: Add missing system calls

Browse Source 
This patch adds all system calls present in riscv-gnu-toolchain at
commit hash 65cb174. Many of them do not have implementations in gem5, so
they are just placeholders.

[Remove the variadic macro and replace it with a function that has
default arguments because variadic macros may not be portable across
compilers]
[Remove spaces around default arguments of createSyscall for better
style]
[Switch from using a loose function to using SyscallDesc's new
constructor]
