include: Remove ilen member of struct unpriv_trap
We simplify struct unpriv_trap by removing ilen member. This
can be achieved by ensuring that at all unpriv load/store
instructions are 4 bytes long using GCC assembler option.
Additionally, this also reduces few instructions from unpriv
load/store functions.
