ata changes for 6.5-rc1 

- Add support for the .remove_new callback to the ata_platform code to
    simplify device removal interface (Uwe).
 
  - Code simplification in ata_dev_revalidate() (Yahu)
 
  - Fix code indentation and coding style in the pata_parport protocol
    modules to avoid warnings from static code analyzers (me)
 
  - Clarify ata_eh_qc_retry() behavior with better comments (Niklas)
 
  - Simplify and improve ata_change_queue_depth() behavior to have a
    consistent behavior between libsas managed devices and libata managed
    devices (e.g. AHCI connected devices) (me).
 
  - Cleanup libata-scsi and libata-eh code to use the ata_ncq_enabled()
    and ata_ncq_supported() helpers instead of open coding flags tests
    (me)
 
  - Cleanup ahci_reset_controller() code (me).
 
  - Change the pata_octeon_cf and sata_svw drivers to use
    of_property_read_reg() to simplify the code (Rob, me).
 
  - Remove unnecessary include files from ahci_octeon driver (me)
 
  - Modify the DesignWare ahci dt bindings to add support for the
    Rockchip RK3588 AHCI (Sebastian).
