flash Kinetis: Implement flash protection setting

Kinetis family employs strange concept of Flash Configuration Field at
address 0x400 of program flash. Writing incorrect data to FCF may
permanently lock the device.

The change introduces 'kinetis fcf_source protection' mode. In this mode
write of flash image data to FCF is prevented. FCF data build from
protection (set by 'flash protect' command) are written instead.

FCF data are written also just after erase of relevant sector. It
protects device from locking security by reset or power cycle after erase.

prot_blocks array is used as protection blocks have bigger size than sectors.

Alignment and padding programming sections is rewritten to fix
writing with not section boundary aligned begin.
