drm/qxl: fix qxl can't use in arm64
qxl use ioremap to map ram_header and rom, in the arm64 implementation,
the device is mapped as DEVICE_nGnRE, it can not support unaligned
access. and qxl is a virtual device, it can be treated more like RAM
than actual MMIO registers. use ioremap_wc() replace it.
