Subject: [PATCH v2 1/5] arm: dts: imx8qm: Remove adma pwm

From: Andrejs Cainikovs <andrejs.cainikovs@...adex.com>

There is no adma pwm on iMX8QM, so remove it from the DT. When enabled,
this cause warnings on resource partition ownership check by U-Boot
that receives messages from SCU firmware saying that these resources are
not owned:

Booting using the fdt blob at 0x9d400000
Loading Device Tree to 00000000fd622000, end 00000000fd66efff ... OK
Disable pwm@...90000 rsrc 188 not owned
Disable clock-controller@...90000 rsrc 188 not owned
