lib: Simplify trap parameters in sbi_ecall functions
The out_tcause and out_tval parameters are not sufficient for most
sbi_ecall functions because this will grow in-future when we support
RISC-V hypervisor v0.5 draft. We replace these parameters with out_trap
which is a pointer to struct sbi_trap_info.
