ar71xx: add an extra check on board_name for ath10k firmware patchs

It moves firmware patch code behind an extra check on board_name.
Otherwise it will calculate firmware checksum for unaffected boards.
It also reduce boottime by a md5 calculation and removes error message
on boot if firmware not found.

SVN-Revision: 43679
