6c01bf6c7b target-ppc: fix fres, fsqrte and remove useless code
- fres and fsqrte should not assign a float32 number to a float64 value.
- fre, fres and fsqrte are checking for cases already taken into account
  by softfloat and softfloat native. Remove those useless tests.

2c9fade200 target-ppc: IBM PowerPC 440EP Bamboo reference board emulation
Since most IO devices are integrated into the 440EP chip, "Bamboo support"
mostly entails implementing the -kernel, -initrd, and -append options.

These options are implemented by loading the guest as if u-boot had done it,
i.e. loading a flat device tree, updating it to hold initrd addresses, ram
size, and command line, and passing the FDT address in r3.

Since we use it with KVM, we enable the virtio block driver and include hooks
necessary for KVM support.

d76d16501e target-ppc: Enable KVM for ppcemb.
Implement hooks called by generic KVM code.

Also add code that will copy the host's CPU and timebase frequencies to the
guest, which is necessary on KVM because the guest can directly access the
timebase.
