[Buildroot] [PATCH] package/freescale-imx: add layerscape platform

[Francois Perrad]

layerscape is not strictly a member of the IMX family,
but the NXP layerscape family uses some of components of the IMX family,
especially the IMX GPU Vivante.

this change allows to use imx-gpu_viv firmware with a layerscape SoC.

  I'm not entirely familiar with the NXP product line, but I do know for sure 
that "layerscape" does not designate a SoC, it's a _line_ of SoCs. Some of them 
are actually PowerPC!

  So you definitely can't have "layerscape at the same level as "IMX8MP". I'd 
rather expect something like LS21XX or something like that.

  It unfortunately pretty much depends on what NXP is going to add later, i.e. 
if they're going to add layerscapes that have a different GPU or VPU.

  This is normally how you know the correct designation, because the platform is 
used in some libraries. But none of them for the Vivante, so in this case 
there's no telling.
