  5. target/xtensa: esp32: enable FPU2000 instructions 

    Xtensa LX6 CPU inside the ESP32 implements a more recent version of
the FPU coprocessor. However QEMU only supports FPU2000, so enable at
least that.

Some floating point instructions which were added after FPU2000 are
still unsupported after this change: sqrt0.s div0.s recip0.s rsqrt0.s
maddn.s divn.s const.s nexp01.s addexp.s addexpm.s mkdadj.s mksadj.s.
