[PATCH v1 20/21] tests/function/aspeed: Replace manual loader with vbootrom for ast2700fc test

[Jamin Lin via <qemu-arm@nongnu.org>]

SSP and TSP now boot in a powered-off state by default. Enabling them requires
the PSP (Cortex-A35) to explicitly set SCU control registers at runtime. This
behavior aligns with real hardware.

However, the current functional test framework design does not support switching
the active VM console after launch. For example, when the PSP is launched first
to enable SSP via SCU, the test framework cannot dynamically attach to the SSP
console afterward to verify its behavior.

Due to this limitation, the test case for AST2700FC has been modified to use
vBootROM (`ast27x0_bootrom.bin`) instead of manually loading boot images and
firmwares via `-device loader`. The vBootROM integrates boot sequencing for
PSP, TSP, and SSP and sets up SCU configuration as part of its flow, enabling
more realistic full-system testing without relying on console switching.
