tcx: avoid structure holes spotted by pahole
Report from pahole on amd64 host:
struct TCXState {
SysBusDevice busdev; /* 0 5648 */
/* --- cacheline 88 boundary (5632 bytes) was 16 bytes ago --- */

uint32_t * vram24; /* 5672 8 */
uint32_t * cplane; /* 5680 8 */
ram_addr_t vram_offset; /* 5688 8 */
/* --- cacheline 89 boundary (5696 bytes) --- */
ram_addr_t vram24_offset; /* 5696 8 */

/* XXX 2 bytes hole, try to pack */
/* --- cacheline 101 boundary (6464 bytes) was 28 bytes ago --- */
uint32_t palette[256]; /* 6492 1024 */
/* --- cacheline 117 boundary (7488 bytes) was 28 bytes ago --- */
uint8_t dac_index; /* 7516 1 */
uint8_t dac_state; /* 7517 1 */
/* size: 7520, cachelines: 118 */
/* sum members: 7516, holes: 1, sum holes: 2 */
/* padding: 2 */
/* last cacheline: 32 bytes */
}; /* definitions: 1 */
Fix by rearranging the structure to avoid padding.
