Pull powerpc updates from Benjamin Herrenschmidt:
 "Kumar sent me a handful of Freescale related fixes and I added another
  regression fix to the pile.

  PS.  I -will- eventually learn about that signed tag business :-)"

* 'merge' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc:
  powerpc/kvm/book3s_32: Fix MTMSR_EERI macro
  powerpc/85xx: p1022ds: fix DIU/LBC switching with NAND enabled
  powerpc/85xx: p1022ds: disable the NAND flash node if video is enabled
  powerpc/85xx: Fix sram_offset parameter type
  powerpc/85xx: P3041DS - change espi input-clock from 40MHz to 35MHz
  powerpc/85xx: Fix pci base address error for p2020rdb-pc in dts
