clk: meson: only build selected platforms
Break the AmLogic clock code up so that only the necessary parts are compiled and linked. The core code is selected by both arm and arm64 builds with COMMON_CLK_AMLOGIC. The individual drivers have their own config options as well. Tested-by: Kevin Hilman <khilman@baylibre.com> Signed-off-by: Michael Turquette <mturquette@baylibre.com>
