FPGA Manager changes for 6.3-final

Intel m10 bmc secure update:
 
 - Ilpo's change fixes the return value of driver internal function
 
 DFL PCI driver:
 
 - Bjorn's change drops redundant pci_enable_pcie_error_reporting()
 
 Xilinx:
 
 - Michal's change uses xlnx_pr_decouple_read() instead of readl() to
   resolve sparse issue.
 
 FPGA core:
 
 - Alexis's change fixes kernel warning on fpga bridge register
 
 All patches have been reviewed on the mailing list, and have been in the
 last linux-next releases (as part of our fixes branch)
