ar71xx: add qihoo 360 c301 router support

Qihoo 360 C301 is a dual band wireless router supports 802.11n and 802.11ac.
Its chipset is AR9344 + AR9882 with two 16MB flashes.

This patch adds its initial support.

v2:
* use mtd_get_mac_ascii to fetch MAC address for ath10k.
* use ath79_register_pci to initialize AR9882.
