clk: Gemini: fix struct name in kernel-doc

Fix a typo in the struct name in the kernel-doc notation so that
kernel-doc won't complain about it.

Fixes this warning:

drivers/clk/clk-gemini.c:64: warning: expecting prototype for struct gemini_data_data. Prototype was for struct gemini_gate_data instead
