bluenrg-x: simplyfied the driver

Browse Source 
Adopted only fast algorithm for flash programming:
- write_word and write_byte methods have been removed.
- start and end write alignments have been defined.
Moved flash controller registers offsets in a common file
shared with the flash algorithm.
- the flash base address is passed to the flash algorithm
  as a parameter.
Removed unused functions
