Takes in a SMC function ID in X0, and arguments for that SMC function in X1-X7.
Passing an invalid SMC function ID or calling from a core other than core 3 will result in a secure monitor panic.
The kernel parses bits 9-15 in the passed SMC function ID (per the ARM SMC calling convention), and when set uses as an indicator to translate a pointer in the associated register (X1-X7) to a physical address. The kernel will translate any address mapped as R-W, other addresses (R--, R-X, or invalid pointers) will be translated as 0/NULL.
Output is returned raw from the Secure Monitor; X0 will be the untranslated SMC result and X1-X7 will contain other SMC output (or be unchanged, depending on the SMC).
