[Stable-8.0.3 26/54] hw/mips/malta: Fix the malta machine on big endian hosts |

From: Thomas Huth <thuth@redhat.com>
Booting a Linux kernel with the malta machine is currently broken
on big endian hosts. The cpu_to_gt32 macro wants to byteswap a value
for little endian targets only, but uses the wrong way to do this:
cpu_to_[lb]e32 works the other way round on big endian hosts! Fix
it by using the same ways on both, big and little endian hosts.
Fixes: 0c8427baf0 ("hw/mips/malta: Use bootloader helper to set BAR registers")
