[PATCH v4 6/7] clk: mediatek: Export required symbols to compile clk drivers as module

[AngeloGioacchino Del Regno <angelogioacchino.delregno@xxxxxxxxxxxxx>]

In order to compile the clock drivers for various MediaTek SoCs as
modules, it is necessary to export a few functions from the MediaTek
specific clocks (and reset) libraries.
