[Michal Simek]

From: T Karthik Reddy <t.karthik.reddy at xilinx.com>

Add distro boot support for microblaze and enable jtag, qspi,
dhcp, pxe boot targets for distro boot.
Enable DISTRO_DEFAULTS config in microblaze defconfig and also
enable support for spi xilinx driver & spi vendors to access
spi flash by distro boot.
