memory: mtk-smi: Add support for MT6795 Helio X10

The MediaTek Helio X10 (MT6795) SoC has 5 LARBs and one common SMI
instance without any sub-common and without GALS.

While the smi-common configuration is specific to this SoC, on the
LARB side, this is similar to MT8173, in the sense that it doesn't
need the port in LARB, and the register layout is also compatible
with that one, which makes us able to fully reuse the smi-larb
platform data struct that was introduced for MT8173.
