Instead of placing FDT (passed by previous booting stage) at a
location relative to next address we should have absolute
location of placing FDT so that we more freedom of placing FDT.
This will be particularly useful for platforms/boards with
very less RAM (such as Kendryte board).
Due to above motivation, we rename FW_xyz_FDT_OFFSET options
to FW_xyz_FDT_ADDR options and use FW_xyz_FDT_ADDR options as
absolute address for placing FDT.

This patch remove hard-coding of payload location in
fw_payload.elf.ldS by adding compile-time option
FW_PAYLOAD_OFFSET.
With the new compile-time option, payload will be placed
at PLAT_TEXT_START + FW_PAYLOAD_OFFSET address.

The QEMU sifive_u machine is not excatly same as HiFive Unleashed
board hence we add separate platform support for QEMU sifive_u
machine.
