storm: Initialize clock, pinmux for NAND if present on board

This patch runs basic NAND initialization code on Proto 0.2 boards which
    have been reworked for NAND. It makes sense to do this in coreboot for
    two reasons:
    - In general, it is reasonable for coreboot to initialize clocks and such
      in preparation for depthcharge's use. Waiting times can be pooled, and
      the initialization itself here is very fast.
    - There is a kernel bug which requires that the clock is already initialized
      before the kernel loads NAND support. coreboot is a more sensible place
      to put a workaround than depthcharge because depthcharge initializes
      things lazily, but when booting from USB, depthcharge won't need to look
      at NAND.
    This change involves bringing in an additional header file, ebi2.h, from U-Boot.

TEST=Booted a kernel from USB and verified that NAND came up without any
    depthcharge hacks, whereas previously a USB-booted kernel would be unable
    to access NAND even with the same drivers compiled in due to an initialization
    failure.
