net: stmmac: use u8 for ?x_queues_to_use and number_?x_queues
The maximum number of queues is a compile time constant of only eight.
This makes using a 32-bit quantity wastefulf. Instead, use u8 for
these and their associated variables.
When reading the DT properties, saturdate at U8_MAX. Provided the core
provides DMA capabilities to describe the number of queues, this will
be capped by stmmac_hw_init() with a warning.
