Add new levelx APIs

New APIs
--------
- lx_nor_flash_format(): erases nor flash blocks and setup block metadata
- lx_nor_flash_open_extended(): same as lx_nor_flash_open() with
  user data pointer a last argument.
- lx_nand_flash_open_extended(): same as lx_nand_flash_open() with
  user data pointer a last argument.

Updates
-------
- lx_nor_flash_open(): calls lx_nor_flash_open_extended() with a NULL as
  last argument
- lx_nand_flash_open(): calls lx_nand_flash_open_extended() with a NULL as
  last argument
- regression tests: to call the lx_nor_flash_format()
