sun4m_iommu: avoid structure holes spotted by pahole
Report from pahole on amd64 host:
struct IOMMUState {
SysBusDevice busdev; /* 0 5648 */
/* --- cacheline 88 boundary (5632 bytes) was 16 bytes ago --- */
uint32_t regs[4096]; /* 5648 16384 */
/* --- cacheline 344 boundary (22016 bytes) was 16 bytes ago --- */
target_phys_addr_t iostart; /* 22032 8 */
uint32_t version; /* 22040 4 */
/* XXX 4 bytes hole, try to pack */
qemu_irq irq; /* 22048 8 */
/* size: 22056, cachelines: 345 */
/* sum members: 22052, holes: 1, sum holes: 4 */
/* last cacheline: 40 bytes */
}; /* definitions: 1 */
Fix by rearranging the structure to avoid padding.
