Romain Perier 689ae6e404 package/amd-catalyst: Add AMD proprietary graphic stack support
This commits adds support for the AMD Catalyst Linux driver 15.9
(15.201.1151). It includes the fglrx kernel module with various fixes
to make it work with at least Linux kernel 4.4 LTS, the userspace OpenGL
stack and the xorg driver module.

[Thomas:
 - fixup whitespace issues noticed by Yann.
 - register AMD_CATALYST_PREPARE_MODULE as a post-patch hook rather than
   calling it during the configure step, also suggested by Yann.]

Subject: [PATCH] Add support for Linux 4.4
It fixes various things like the use of seq_printf because its API
changed. It also replaces the call to mtrr_add and mtrr_del by
arch_phys_wc_add and arch_phys_wc_del because these symbols are
no longer exported for Linux >= 4.3.x.
