e18fcbba5a device: Const-ify all device driver instance pointers 
Now that device_api attribute is unmodified at runtime, as well as all
the other attributes, it is possible to switch all device driver
instance to be constant.

A coccinelle rule is used for this:

@r_const_dev_1
  disable optional_qualifier
@
@@
-struct device *
+const struct device *

@r_const_dev_2
 disable optional_qualifier
@
@@
-struct device * const
+const struct device *

Fixes #27399

1e6679a23b drivers: console: uart_mux: consume ringbuf until it is empty 
ringbuf claim API returns pointer to contiguous area. In cases when data
in ringbuf wraps the end of internal buffer, then single call to claim
data is not enough to get all data - there is remaining part on the
beginning of internal buffer. Those remaining bytes will need to wait
for next ISR handler to trigger workqueue. Theoretically this means that
data on the beginning of ringbuf can wait there forever.

Consume data from ringbuf in a loop, stopping only when claiming results
in empty buffer. This will make sure that there is no stale data in the
ringbuf.
