lib: sbi_ecall: Remove mcause, scratch and hartid parameters
We remove mcause, scratch and hartid parameters from various functions for ecall handling because we can always get current HART id and current scratch pointer using just one CSR access. Signed-off-by: Anup Patel <anup.patel@wdc.com> Reviewed-by: Atish Patra <atish.patra@wdc.com>
