Subject: sb/amd/cimx: replace cimx_util with common ACPIMMIO AMD block
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Drop the redundant cimx_util, remove the includes when appropriate and
replace the implementation with amdblocks/acpimmio where needed.

TEST=boot PC Engines apu1 and launch Debian with Linux kernel 4.14.50
