RISC-V: Export SBI error to linux error mapping function

Browse Source 
All SBI related extensions will not be implemented in sbi.c to avoid
bloating. Thus, sbi_err_map_linux_errno() will be used in other files
implementing that specific extension.

Export the function so that it can be used later.
