MIPS: eBPF: Provide eBPF support for MIPS64R6
Currently eBPF support is available on MIPS64R2 only. Use MIPS64R6
variants of instructions like multiply, divide, movn, movz so eBPF
can run on the newer ISA. Also, we only need to check ISA revision
before JIT'ing code, because we know the CPU is running a 64-bit
kernel because eBPF JIT is only included in kernels with CONFIG_64BIT=y
due to Kconfig dependencies.
