configs: stih410-b2260: Enable DM_REGULATOR flag

Since commit 6aa8bde8786d ("usb: host: ehci-generic: Remove DM_REGULATOR
flag") device_get_supply_regulator() returns -ENOSYS which is not handle
by ehci_enable_vbus_supply() and thus, ehci_usb_probe() return an error.

By enabling DM_REGULATOR flag, device_get_supply_regulator() return -ENOENT
which is handle and ehci_usb_probe() return 0.

This fixed the following issue:
