firmware: Remove FW_PAYLOAD_FDT_PATH compile-time option

Browse Source 
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

This is because QEMU generates a device tree blob on the fly based on the
