firmware: Remove FW_PAYLOAD_FDT_PATH compile-time option

The FW_PAYLOAD_FDT_PATH compile-time option is replaced by
FW_FDT_PATH compile-time option which is more flexible and
common across all OpenSBI firmwares.

This patch removes FW_PAYLOAD_FDT_PATH and updates related
documentation to use FW_FDT_PATH.

QEMU Specific Instructions
--------------------------
If you want to test OpenSBI with QEMU 'sifive_u' machine, please follow the
same instructions above, with the exception of not passing FW_PAYLOAD_FDT_PATH.
