MIPS: use generic-y where possible

Use generic-y and remove headers in arch/mips/include/[uapi/]asm/Kbuild
where the header just includes or is identical to the corresponding
<asm-generic/*.h>.

We can't do the same for uapi/asm/kvm_para.h because it's presence is
explicitly checked in include/uapi/linux/Kbuild to decide whether to add
kvm_para.h to header-y.
