Description:
This patch is to 

1) Enable independent PERST support in F-Tile Avalon (R) Streaming Intel (R) FPGA IP for PCI Express* IP.
    When independent PERST is enabled, Debug Toolkit, PHY reconfiguration interface and Hard IP reconfiguration interface
    are not supported when either pin_perst_n or i_gpio_perst#_n is asserted.

2) Fix the following Debug Toolkit issues:
   - Debug Toolkit reports error when users click Lane refresh under Channel Parameters for designs in 1x4 mode.
   - Debug Toolkit BAR1 under Configuration Space tab shows IO space.

Caution - You must either have previously installed the
          Intel(R) Quartus(R) Prime 21.4 software or must
          install the Intel(R) Quartus(R) Prime 21.4 software
          before installing this patch. Otherwise, the patch will
          not be installed correctly and the Intel(R) Quartus(R) Prime
          software will not run properly.
