[LEDE-DEV] [PATCH] firmware-utils: mktplinkfw2: update firmware header

Sun Jul 2 04:29:26 PDT 2017
From: Rafał Miłecki <rafal at milecki.pl>
1) Be consistent and use tabs
2) Drop FIXME from boot comments - some images use these fields normally
3) Add V3 specific fields (signatures)
4) Add V3.0.0.3 region field
