364d480242 hw/xtensa/xtfpga: implement uImage loading 
Provide a simple bootloader code at the reset address that jumps to the
loaded image entry point when it's not equal to the reset address. This
is needed because the old method of setting pc doesn't work due to cpu
reset done after the machine setup.

While at it rename lx60 (named after the first board of the family) to
more generic xtfpga (the family name).
