brcm63xx: initial support for Sky SR102 router

The sender domain has a DMARC Reject/Quarantine policy which disallows
sending mailing list messages using the original "From" header.

To mitigate this problem, the original message has been wrapped
automatically by the mailing list software.
SOC: 	    BCM63168 (BMIPS4350 V8.0 @400MHz)
Flash size: 16 MiB
RAM size:   128 MiB

Heavily based on patch for OpenWRT Chaos Chalmer.
Original patch and more info can be found at:
https://openwrt.org/toh/sky/sr102

Known issues:
 - Wireless and ADSL modem are not working.
