media: hantro: add fallback handling for single irq/clk

Browse source

Currently the driver expects that each irq/clk will have a name
specified.

A valid point was raised by the DT maintainers - when there is a single
interrupt line or clock - the names are not needed.

Keep the names within the drivers themselves, but don't use them when
only a single entry exists. Instead use:
 - num_clk == 1 - devm_clk_get(..., NULL)
 - num_irq == 1 - platform_get_irq(..., 0)
