Subject: [PATCH v3 0/3] fbdev: kyro: Convert to managed device resources

This series aims to address the TODO item "Request memory regions in all
fbdev drivers" from Documentation/gpu/todo.rst.
Additionally, it also converts the kyro framebuffer driver to use managed device
functions.

In summary, it converts the driver to use:
1. Managed PCI device enable and region request functions
2. Managed ioremap for MMIO registers  
3. Managed ioremap_wc for screen memory

This simplifies error handling and removes the need for manual cleanup
in the remove function.

Changes in v3:
- Split into a patch series as suggested by Thomas Zimmermann [1]
- Convert ioremap calls to devm_ variants

Changes in v2:
- Use pcim_enable_device() instead of pci_enable_device()
- Use pcim_request_all_regions() instead of pci_request_regions()
- Removed manual cleanup code as it's now automatic

  fbdev: kyro: Add missing PCI memory region request
  fbdev: kyro: Use devm_ioremap() for mmio registers
  fbdev: kyro: Use devm_ioremap_wc() for screen mem
