[U-Boot-Users] [PATCH] fsl_pci_init Fix command register initialization issue.

[U-Boot-Users] [PATCH] fsl_pci_init Fix command register initialization issue.

[Jason Jin]

Use generic setup_device to initialize standard pci regs
for the host will lost the initilization for the command
register. This patch initilize those regs including
command register directly.
