[PATCH] sunxi: h616: add initial support for T95 AXP313 TV Box

[Kamil Kasperski <ressetkk@gmail.com>]

T95 is a most commonly known for being a box with a pre-installed malware.
It uses Allwinner H616 and comes with eMMC and DDR3 memory.
This device comes with two versions - one with AXP305 PMIC and another with AXP313 PMIC.
The AXP313 version comes with Secure Boot enabled and locked bootloader, so the u-boot has to be built with TOC0.
DRAM settings are taken from Allwinner's boot0 for this box.
