Subject: [PATCH] soc: mediatek: mtk-mmsys: Add support for MT6795 Helio X10

Add MM support for the MT6795 SoC, using the mmsys default routing
table.

Signed-off-by: AngeloGioacchino Del Regno <angelogioacchino.delregno@...labora.com>

In order for this patch to have any meaning and functionality, it is
required to also have in-tree the [1] MT6795 clocks series, even
though that's not required to actually compile this code.
