ata changes for 6.19-rc1

- Add DT binding for the Eswin EIC7700 SoC SATA Controller (Yulin Lu)
 
  - Allow 'iommus' property in the Synopsys DWC AHCI SATA controller
    DT binding (Rob Herring)
 
  - Replace deprecated strcpy with strscpy in the pata_it821x driver
    (Thorsten Blum)
 
  - Add Iomega Clik! PCMCIA ATA/ATAPI Adapter PCMCIA ID to the
    pata_pcmcia driver (René Rebe)
 
  - Add ATA_QUIRK_NOLPM quirk for two Silicon Motion SSDs with broken
    LPM support (me)
 
  - Add flag WQ_PERCPU to the workqueue in the libata-sff helper
    library to explicitly request the use of the per-CPU behavior
    (Marco Crivellari)
