Introduce a vector table to provide a predictable behavior when
exceptions are raised before the Rust runtime is ready i.e. before
vector_table_el1 may be used. With this table, exceptions are "handled"
by attempting a PSCI_SYSTEM_RESET call and hanging if that returns. For
example, this may prevent a malicious host from triggering a fault when
entry.S accesses .data or .bss in entry.S and getting arbitrary code
execution from VBAR_EL1.
