flash/nor: improved API of flash_driver.info & fixed buffer overruns

Browse Source 
1) The API of "info" callback in "struct flash_driver" has been
improved. Fixed buffers for strings

2) Removed the calls to snprintf() from the flash_driver.info
implementations. Many of them were used in an unsafe manner
(buffer overruns were possible).
