[PATCH] ARC: HSDK: improve reset driver

From: Eugeniy Paltsev
Date: Mon Aug 27 2018 - 10:38:12 EST

As for today HSDK reset driver implements only
.reset() callback.

In case of driver which implements one of standard
reset controller usage pattern
(call *_deassert() in probe(), call *_assert() in remove())
that leads to inoperability of this reset driver.

Improve HSDK reset driver by calling .reset() callback inside of
.assert()/.deassert() callbacks to avoid each reset controller
user adaptation for work with both reset methods
(reset() and .assert()/.deassert() pair)
