bcm53xx: add support for TP-LINK Archer C5 V2

Browse Source 
This model also contains few partitions non-discoverable partitions we
need to "protect". Othen than that it uses non-deprecated serial entry
in DTS that doesn't work with LEDE so we need to workaround it as well.

Subject: [PATCH] ARM: dts: BCM5301X: Add serial= to the bootargs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
It's enough to have proper stdout-path for getting serial working but
for some reason LEDE doesn't offer "Please press Enter to activate this
console." unless ttyS0 is specified.
This is a workaround to get serial working in LEDE.
