[PATCHv3 1/2] PCI: layerscape: Add the bar_fixed_64bit property in EP driver.

From: Xiaowei Bao <hidden>
Date: 2019-06-28 01:47:49
Also in: linux-devicetree, linux-pci, linuxppc-dev, lkml
Subsystem: pci driver for freescale layerscape, pci native host bridge and endpoint drivers, pci subsystem, the rest · Maintainers: Minghuan Lian, Mingkai Hu, Roy Zang, Lorenzo Pieralisi, Krzysztof Wilczyński, Manivannan Sadhasivam, Bjorn Helgaas, Linus Torvalds

The PCIe controller of layerscape just have 4 BARs, BAR0 and BAR1
is 32bit, BAR3 and BAR4 is 64bit, this is determined by hardware,
so set the bar_fixed_64bit with 0x14.

Signed-off-by: Xiaowei Bao <redacted>

v2:
 - Replace value 0x14 with a macro.
v3:
 - No change.
