clk: samsung: clk-exynos-audss: Fix module autoload

commit 34b89b2967f284937be6759936ef3dc4d3aff2d0 upstream.

If the driver is built as a module, autoload won't work because the module
alias information is not filled. So user-space can't match the registered
device with the corresponding module.

Export the module alias information using the MODULE_DEVICE_TABLE() macro.

Before this patch:

$ modinfo drivers/clk/samsung/clk-exynos-audss.ko | grep alias
alias:          platform:exynos-audss-clk

After this patch:

$ modinfo drivers/clk/samsung/clk-exynos-audss.ko | grep alias
alias:          platform:exynos-audss-clk
alias:          of:N*T*Csamsung,exynos5420-audss-clockC*
alias:          of:N*T*Csamsung,exynos5420-audss-clock
alias:          of:N*T*Csamsung,exynos5410-audss-clockC*
