Subject: [PATCH AUTOSEL 5.3 12/49] PCI: layerscape: Add the bar_fixed_64bit property to the endpoint driver

From: Xiaowei Bao <xiaowei.bao@....com>

[ Upstream commit fd5d16531a39322c3d7433d9f8a36203c9aaeddc ]

The layerscape PCIe controller have 4 BARs.

 BAR0 and BAR1 are 32bit, BAR2 and BAR4 are 64bit and that's a
fixed hardware configuration.

Set the bar_fixed_64bit variable accordingly.
