[PATCH] powerpc: platforms: powernv: include "asm/prom.h" in "rng.c"

[Chen Gang <gang.chen@asianux.com>]

Need include the related header file, or can not pass compiling with
allmodconfig.

The related error (with allmodconfig):

    CC      arch/powerpc/platforms/powernv/rng.o
  arch/powerpc/platforms/powernv/rng.c: In function ‘rng_init_per_cpu’:
  arch/powerpc/platforms/powernv/rng.c:64:2: error: implicit declaration of function ‘of_get_ibm_chip_id’ [-Werror=implicit-function-declaration]
