[PATCH 2/3] arm64: fpsimd: Abstract out binding of task's fpsimd context to the cpu.

There is currently some duplicate logic to associate current's FPSIMD context with the cpu when loading FPSIMD state into the cpu regs. Subsequent patches will update that logic, so in order to ensure it only needs to be done in one place, this patch factors the relevant code out into a new functi
