[meta-xilinx] [PATCH 07/12] linux/configs: Split PCIe drivers off from zynq7 config fragment

[Nathan Rossi]

The PCIe drivers for the Xilinx AXI PCIe bridge are only available on
Zynq targets when have the soft core loaded, for all other targets this
driver is not required.

To optimized the kernel for general use make the PCIe driver a seperate
fragment which can be enabled by adding
'bsp/xilinx/soc/drivers/xilinx-pcie.scc' to KERNEL_FEATURES.

Also add to the config fragment the required kernel options to enable
PCI.
