bcm53xx: add support for TP-LINK Archer C5 V2
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. Signed-off-by: Rafał Miłecki <rafal@milecki.pl>

+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.
