fvp: Update instructions for building the bootloader
A new bootloader-only configuration has recently been added to the
reference platform stack, update the instructions accordingly.
This brings the following improvements:
- Much smaller tree (therefore faster to sync).
- Much faster to build, as only the relevant projects (U-Boot and
TF-A) are built.
- No need to download the 32-bit toolchain any more (all the
components are 64-bit only).
Test: boot fvp-eng using the updated instructions

These components must then be copied into the product output directory:
```
