Merge branch 'keystone/soc' into next/soc

From Santosh Shilimkar:
* keystone/soc:
  ARM: keystone: defconfig: enable USB support
  ARM: keystone: Avoid calling of_clk_init() twice
  ARM: keystone: Make PM bus ready before populating platform devices
  ARM: keystone: enable DMA zone for LPAE
  ARM: keystone: enable big endian support
