[PATCH v3 2/3] fbdev: kyro: Use devm_ioremap() for mmio registers

[Giovanni Di Santi]

Replace the manual ioremap() call for the MMIO registers with the
device-managed devm_ioremap() variant.

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