[meta-freescale] imx-m4-demos made comeback in Thud

[Teemu K]

Hi,

I've been using meta-freescale hash
a589464469cfbe7049ec6fb47cf662047044e6e3 and it's been working quite
fine.

Now I updated to latest hash 85561882cc455ccf45ddb16039fa3811cf7baa8b
and imx-m4-demos have made comeback and build fails on an error:

ERROR: Nothing PROVIDES 'imx-m4-demos'

I was looking old messages and there was patch to remove it late
January and then comment that it's not the right way. So how should
the imx-m4-demos to be dealt with? Atm. latest meta-freescale is
non-buildable at least for imx8qxp.
