f0682623ca fm4: Add support for S6E2DH family
Add support for S6E2DH MainFlash. VFlash is not implemented.

Briefly tested with SK-FM4-176L-S6E2DH V110 board.

f2b3a8b0e8 fm4: Add support for MB9BFx64/x65
These appear to be just additional flash size configurations.
Entirely based on manual, untested.

43ff5acd45 flash: New Spansion FM4 flash driver
The Spansion FM4 family of microcontrollers does not offer a way to
identify the chip model nor the flash size, except for Dual Flash vs.
regular layout. Therefore the family is passed as argument and
wildcard-matched - MB9BFx6x and S6E2CC families are supported.

Iterations showed that ...
1) Just doing the flash command sequence from SRAM loader code for each
half-word took 20 minutes for an 8 KB block.
2) Doing the busy-wait in the loader merely reduced the time to 19 minutes.
3) Significant performance gains were achieved by looping in loader code
rather than in OpenOCD and by maximizing the batch size across sectors,
getting us down to ~2 seconds for 8 KB and ~2.5 minutes for 1.1 MB.
(Tested with SK-FM4-176L-S6E2CC-ETH v11, CMSIS-DAP v23.)

gcc, objcopy -Obinary and bin2char.sh are used for automating the
integration of hand-written assembler snippets.
