Subject: [PATCH 4.19 411/639] clk: sunxi-ng: sun50i-h6-r: Fix incorrect W1 clock gate register

From: Ondrej Jirman <megous@...ous.com>

[ Upstream commit f167675486c37b88620d344fbb12d06e34f11d47 ]

The current code defines W1 clock gate to be at 0x1cc, overlaying it
with the IR gate.

Clock gate for r-apb1-w1 is at 0x1ec. This fixes issues with IR receiver
causing interrupt floods on H6 (because interrupt flags can't be cleared,
due to IR module's bus being disabled).

Fixes: b7c7b05065aa77ae ("clk: sunxi-ng: add support for H6 PRCM CCU")
