metag: minimal TZ1090 (Comet) SoC infrastructure

Browse Source 
Add really minimal support for Toumaz Xenif TZ1090 SoC (A.K.A. Comet).
This consists of minimal build infrastructure, device tree files, and a
defconfig based on meta2_defconfig.

This SoC contains a 2-threaded HTP (Meta 2) as the main application
processor, and is found in a number of development boards and digital
radios, such as the Minimorph Development Platform.
