Add a v5l2 cache controller driver that is usually found on
Andes RISC-V ae350 platform. It will parse the cache settings
from the dtb.
In this version tag and data ram control timing can be adjusted
by the requirement from the dtb.

Add a PL310 cache controller driver that is usually found on
ARMv7(32-bit) devices. The driver configures the cache settings that can
be found in the device tree files.
This initial revision only configures basic settings(data & instruction
prefetch, shared-override, data & tag latency). I believe these are the
settings that affect performance the most. Comprehensive settings can be
done by the OS.

in a CPU's L2 cache controller.
Add a uclass and a test for cache.
