[PATCH] rtc: hym8563: include clkout code only if COMMON_CLK active

[Heiko Stübner]

The contents of clk-provide.h, struct clk_hw etc, are only available
if CONFIG_COMMON_CLK is selected. Therefore IS_ENABLED(COMMON_CLK) is
not sufficient and real preprocessor conditions are necessary to
keep the code in question from being compiled on non-COMMON_CLK systems.
