GCC compiler complains with below messages.

   warning: ‘ghash_cpu_feature’ defined but not used [-Wunused-const-variable=]
   static const struct cpu_feature ghash_cpu_feature[] = {
			    ^~~~~~~~~~~~~~~~~

The variable with MODULE_DEVICE_TABLE() is registered as platform_driver.
But ghash_cpu_feature is not used, so remove ghash_cpu_feature.
