Subject: [PATCH 4.16 114/279] reset: uniphier: fix USB clock line for LD20

4.16-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Masahiro Yamada <yamada.masahiro@...ionext.com>

[ Upstream commit e6914365fd280fce303a89b8a8d4529af5a2e0f9 ]

For LD20, the bit 5 of the offset 0x200c turned out to be a USB3
reset.  The hardware document says it is the GIO reset despite LD20
has no GIO bus, confusingly.

Also, fix confusing comments for PXs3.
