[PATCH v3 3/3] fbdev: kyro: Use devm_ioremap_wc() for screen mem

[Giovanni Di Santi]

Replace the manual pci_ioremap_wc() call for mapping screen memory with the
device-managed devm_ioremap_wc() variant.

This simplifies the driver's resource management by ensuring the memory is
automatically unmapped when the driver detaches from the device.
