watchdog: dm: Change uclass name to watchdog and enable DM_UC_FLAG_SEQ_ALIAS

Browse source 
uclass name is used by dev_read_alias_seq which return seq number when
aliases are used.

Code fragment:
168 int dev_read_alias_seq(struct udevice *dev, int *devnump)
169 {
170         ofnode node = dev_ofnode(dev);
171         const char *uc_name = dev->uclass->uc_drv->name;
172         int ret;
173
174         if (ofnode_is_np(node)) {
175                 ret = of_alias_get_id(ofnode_to_np(node), uc_name);

Also this patch enables DM_UC_FLAG_SEQ_ALIAS to be in sync with Linux
which is also using watchdog name for watchdog aliases.

drivers/watchdog/watchdog_core.c:215:
 ret = of_alias_get_id(wdd->parent->of_node, "watchdog");
