hw/arm/boot: assert that secure_boot and secure_board_setup are false for AArch64
Add some assertions that if we're about to boot an AArch64 kernel,
the board code has not mistakenly set either secure_boot or
secure_board_setup. It doesn't make sense to set secure_boot,
because all AArch64 kernels must be booted in non-secure mode.
It might in theory make sense to set secure_board_setup, but
we don't currently support that, because only the AArch32
bootloader[] code calls this hook; bootloader_aarch64[] does not.
Since we don't have a current need for this functionality, just
assert that we don't try to use it. If it's needed we'll add
it later.
