[PATCH V2 2/2] clk: imx: imx7d: Remove ARM_M0 clock

From: Adriana Reus <hidden>
Date: 2017-07-20 15:06:42
Also in: linux-clk, linux-devicetree
Subsystem: common clk framework, nxp i.mx clock drivers, open firmware and flattened device tree bindings, the rest · Maintainers: Michael Turquette, Stephen Boyd, Abel Vesa, Rob Herring, Krzysztof Kozlowski, Conor Dooley, Linus Torvalds

IMX7d does not have an M0 Core and this particular
clock doesn't seem connected to anything else.
Remove this entry from the CCM driver.

Signed-off-by: Adriana Reus <redacted>
---
 Changes since v1:
 - left defines alone as to not break potential raw value
   usage. Removed entries from the driver only and added comments
   to mark the unused defines.
