This patch extends fw_payload blob to provide FW_PAYLOAD_FDT_PATH
option using which we can embed custom FDT in .text section of
fw_payload blob. In other words, FW_PAYLOAD_FDT_PATH is an option
to forcefully override FDT passed by previous booting stage in
a1 register.

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.

The PLAT_TEXT_START is only used by our firmware blobs hence
rename it to FW_TEXT_START.

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.
