Subject: [PATCH 1/2] clk: fixed: Remove Allwinner A10 special-case logic

This compatible is part of the legacy sunxi clock support, and has not
been used since commit 6b48644b1d29 ("ARM: gr8: Convert to CCU") in
October 2016. Since supporting this compatible adds some overhead to
generic clock code, let's clean it up.
