habanalabs: fix F/W download in BE architecture
writeX macros might perform byte-swapping in BE architectures. As our F/W is in LE format, we need to make sure no byte-swapping will occur. There is a standard kernel function (called memcpy_toio) for copying data to I/O area which is used in a lot of drivers to download F/W to PCIe adapters. That function also makes sure the data is copied "as-is", without byte-swapping. This patch use that function to copy the F/W to the GOYA ASIC instead of writeX macros.
