Kernel: Make all Spinlocks use u8 for storage, remove template
The default template argument is only used in one place, and it looks like it was probably just an oversight. The rest of the Kernel code all uses u8 as the type. So lets make that the default and remove the unused template argument, as there doesn't seem to be a reason to allow the size to be customizable.
