samd/boards/SAMD_GENERIC_D51xxx: Fix VFS settings for internal flash.

Browse source 
Fixes in this commit:
- The wrong loader script was assigned for SAMD_GENERIC_D51X20, causing the
  VFS block count to be wrong.
- Change the VFS block size from 1536 to 2048.  With the setting of 1536,
  writing more that 1536 bytes at once failed.  This applies to
  SAMD_GENERIC_D51X19 and SAMD_GENERIC_D51X20.  No other SAMD51 board uses
  the internal flash for the file system.
