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.

Update the AST2700 FC functional test to reflect this behavior by enabling
SSP and TSP from the U-Boot shell before booting OpenBMC. The test now
programs the required SCU registers, saves the environment, and boots the
system so that SSP and TSP are powered on when the PSP starts.

For the vbootrom test case, these steps are not required because vbootrom
already performs the necessary initialization. Therefore, the U-Boot shell
configuration is only applied to the manual loader test flow.

Additionally, switch SSP and TSP loading from ELF-based CPU loaders to
binary images loaded into PSP DRAM at fixed addresses, and remove the use
of snapshot mode.

Changes include:
- Add enable_ssp_tsp() to configure SCU registers via U-Boot
- Remove snapshot option from QEMU command line
- Load SSP binary at DRAM address 0x42C000000
- Load TSP binary at DRAM address 0x42E000000
