Subject: [PATCH v6 6/7] reset: mediatek: Add MT2701 reset driver

From: Shunli Wang <shunli.wang@...iatek.com>

In infrasys and perifsys, there are many reset
control bits for kinds of modules. These bits are
used as actual reset controllers to be registered
into kernel's generic reset controller framework.
