movb is used for registers STATUS and CFGGENERATION whose size is 1
byte. Previously hv cannot report the correct MMIO trap size for
movb and virtio hard coded their size to 4 as a workaround. hv fixed
movb instruction emulation and MMIO size can be reported correctly.
This patch removes those workaround.
