arm: tcg: Adhere to SMCCC 1.3 section 5.2
The SMCCC 1.3 spec section 5.2 says
The Unknown SMC Function Identifier is a sign-extended value of (-1)
that is returned in the R0, W0 or X0 registers. An implementation must
return this error code when it receives:
* An SMC or HVC call with an unknown Function Identifier
* An SMC or HVC call for a removed Function Identifier
* An SMC64/HVC64 call from AArch32 state
To comply with these statements, let's always return -1 when we encounter
an unknown HVC or SMC call.
