Input: wistron - declare keymaps as initdata

Browse Source 
As the number of keymaps increases and is very unlikely to
reduce, this patch helps to reduce memory consumption by
declaring all keymaps as __initdata and copying right keymap
during DMI detection. On x86 this make the module size at
runtime going from 10616 to 9428: a bit more than 1kb saved.
