Subject: [PATCH AUTOSEL 4.19 125/252] reset: uniphier: Add SCSSI reset control for each channel

From: Kunihiko Hayashi <hayashi.kunihiko@...ionext.com>

[ Upstream commit f4aec227e985e31d2fdc5608daf48e3de19157b7 ]

SCSSI has reset controls for each channel in the SoCs newer than Pro4,
so this adds missing reset controls for channel 1, 2 and 3. And more, this
moves MCSSI reset ID after SCSSI.

Fixes: 6b39fd590aeb ("reset: uniphier: add reset control support for SPI")
