fix(fvp): disable reclaiming init code by default

In anticipation of Spectre BHB workaround mitigation patches, we
disable the RECLAIM_INIT_CODE for FVP platform. Since the spectre
BHB mitigation workarounds inevitably increase the size of the various
segments due to additional instructions and/or macros, these segments
cannot be fit in the existing memory layout designated for BL31 image.
The issue is specifically seen in complex build configs for FVP
platform. One such config has TBB with Dual CoT and test secure
payload dispatcher(TSPD) enabled. Even a small increase in individual
segment size in order of few bytes might lead to build fails due to
alignment requirements(PAGE_ALIGN to 4KB).

This is needed to workaround the following build failures observed
across multiple build configs:

aarch64-none-elf-ld.bfd: BL31 init has exceeded progbits limit.

aarch64-none-elf-ld.bfd: /work/workspace/workspace/tf-worker_ws_2/trusted_firmware/build/fvp/debug/bl31/bl31.elf section coherent_ram will not fit in region RAM
aarch64-none-elf-ld.bfd: BL31 image has exceeded its limit.
aarch64-none-elf-ld.bfd: region RAM overflowed by 4096 bytes
