hw/xtensa/xtfpga: treat uImage load address as virtual

U-boot for xtensa always treats uImage load address as virtual address.
This is important when booting uImage on xtensa core with MMUv2, because
MMUv2 has fixed non-identity virtual-to-physical mapping after reset.

Always do virtual-to-physical translation of uImage load address and
load uImage at the translated address. This fixes booting uImage kernels
on dc232b and other MMUv2 cores.
