[PATCH] mtd: nand: add FSL_SOC dependency to drivers using FSL_LBC

[Brian Norris <computersforpeace@gmail.com>]

I've managed to construct .config files (for ppc64) that come across
this Kconfig warning:

  warning: (MPC836x_RDK && MTD_NAND_FSL_ELBC && MTD_NAND_FSL_UPM) selects FSL_LBC which has unmet direct dependencies (FSL_SOC)

Let's add the FSL_SOC dependency to the NAND drivers. AFAICT, they are
only supported on PPC32 FSL SoCs anyway.
