Subject: [PATCH 4.16 235/272] ARM: dts: bcm283x: Fix probing of bcm2835-i2s

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

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

From: Stefan Wahren <stefan.wahren@...e.com>

[ Upstream commit 79c81facdc0b43b1cef37b8d5689a8c8b78f8be0 ]

Since 517e7a1537a ("ASoC: bcm2835: move to use the clock framework")
the bcm2835-i2s requires a clock as DT property. Unfortunately
the necessary DT change has never been applied. While we are at it
also fix the first PCM register range to cover the PCM_GRAY register.
