accel: Move target-agnostic code from accel-target.c -> accel-common.c
Various methods of accel-target.c don't use any target-specific knowledge at all and can be built once in the target-agnostic accel-common.c file. Signed-off-by: Philippe Mathieu-Daudé <philmd@linaro.org> Reviewed-by: Pierrick Bouvier <pierrick.bouvier@linaro.org> Message-Id: <20250417165430.58213-8-philmd@linaro.org>
