[RFC PATCH] ARM: dts: imx: replace underscore with hyphen in aliases name

[Shawn Guo <shawnguo@kernel.org>]

It replaces underscore with hyphen in aliases name to fix DTC
alias_paths warning below, which is seen with various i.MX board dts
files when W=1 switch is on.

 Warning (alias_paths): /aliases: aliases property name must include only lowercase and '-'

Hi Lothar, Gary,

Per my search on kernel code, this change will not break anything on
kernel support.  But I'm not really sure about the case of bootloaders
running on the boards.  That's why I'm sending it as RFC.

We really want i.MX to be the first-class citizen in the community.
After a few cycles efforts on cleaning up DTC warnings, this alias_paths
warning is the last one we see with i.MX dts files.  We really want to
get rid of it and make i.MX dts be DTC warning free.

So please comment whether we can merge this patch.

Shawn
