[PATCH v6 21/24] thermal/drivers/uniphier: convert to use devm_request*_irq_probe()

From: Yangtao Li <frank.li at vivo.com>

The new devm_request_*irq_probe API prints an error message by default
when the request fails, and consumers can provide custom error messages.

Converting drivers to use this API has the following benefits:

  1.More than 2,000 lines of code can be saved by removing redundant error
  messages in drivers.

  2.Upper-layer functions can directly return error codes without missing
  debugging information.

  3.Having proper and consistent information about why the device cannot
  be used is useful.
