Subject: [PATCHv4 1/2] PCI: layerscape: Add the bar_fixed_64bit property in EP driver.

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 <xiaowei.bao@....com>

v2:
 - Replace value 0x14 with a macro.
v3:
 - No change.
v4:
 - send the patch again with '--to'.
