lib: sbi_trap: Simplify sbi_trap_handler() API

Browse Source 
This patch simplify sbi_trap_handler() API as follows:
1. Remove current hartid local variable because sbi_trap_handler()
   itself does not need it.
2. Remove scratch parameter because none of the functions directly
   called by sbi_trap_handler() require it.
