The payload for FW_PAYLOAD needs to be placed at a 2M/4M aligned address
(for 64/32 bit systems) and the current makefile uses FW_PAYLOAD_OFFSET
to achieve this. This only works if FW_TEXT_START is already 2M/4M
aligned. Most existing physical/virtual platforms have used a
FW_TEXT_START of 0x0 or 0x80000000, so this hasn't been an issue so far.
If, for example, FW_TEXT_START is 0x80000, the payload would end up
placed at 0x280000 on a 64 bit system, which isn't a 2M aligned
address.
Update the makefile to use FW_PAYLOAD_ALIGN instead. This will ensure
that the address picked for the payload is 2M/4M aligned irrespective of
where FW_TEXT_START is.

Now opensbi can run at any address via dynamic relocation. We can
remove FW_TEXT_START.

Since jump and payload firmware support relocatable address, make
general platform use runtime relocatable address.

The options defined in config.mk can be specified in objects.mk of each
platform so let us remove config.mk from all platforms.

Now that no platform is using FW_PAYLOAD_FDT mechanism, we
remove related code from Makefile and related documentation.
