flash/nor: fix doc/help and range test for flash protect
Commit 77a1c01ccbb1150ffe749a7373cf6c4dc15ecad0 introduced infrastructure for utilizing protection blocks of different size than erase sector. Parts of doc/help kept reading 'sector' instead of 'protection block'. flash_driver_protect() parameter range testing did not switched to bank->num_prot_blocks. This change fixes it.
