[PATCH] Add partial support for Renesas MCUs with RV40F

[Miloslav S. <sem...@mo...>]

Hi all,

this patch contain support for programming/erasing MCUs with RV40F type 
memory inside (RA6M1, RA6M2, RA6M3, RA6T1 series).

Erasing and programming worked on R6AM2 MCUs.

Locking/unlocking not implemented. Only programming/erasing of memory 
working.
