[isar-cip-core][PATCH v2 13/13] start-qemu.sh: Add support for SWUpdate and secure boot mode to arm64

[Jan Kiszka <jan.kiszka@siemens.com>]

From: Jan Kiszka <jan.kiszka@siemens.com>

We just need to pick up the newly deployed firmware.bin as -bios,
analogously to the x86's OVMF, and switch to a disk image. A separate
key storage is not yet used, thus there is no difference between normal
and secure mode for arm64 so far.
