Provide kernel_fpu_begin()/kernel_fpu_end() to allow the kernel itself
to use fpu. They can be used by some other kernel components, e.g., the
AMDGPU graphic driver for DCN.
Since kernel is compiled with -msoft-float, I guess hw fpu will not be
used in kernel by present:). However it is deserved to try.
This has been explained by Ruoyao, but we'd need such support anyway
when we have LSX/LASX support mainlined in the future and want to
accelerate various algorithms with those instructions. Maybe at that
time you'll want to port some of those too ;-)
