[PATCH v3,2/4] powerpc: sysdev: fix compile error for fsl_85xx_cache_sram

[Wang Wenhu]

Include linux/io.h into fsl_85xx_cache_sram.c to fix the
implicit-declaration compile error when building Cache-Sram.

arch/powerpc/sysdev/fsl_85xx_cache_sram.c: In function âinstantiate_cache_sramâ:
arch/powerpc/sysdev/fsl_85xx_cache_sram.c:97:26: error: implicit declaration of function âioremap_coherentâ; did you mean âbitmap_complementâ? [-Werror=implicit-function-declaration]
  cache_sram->base_virt = ioremap_coherent(cache_sram->base_phys,
                          ^~~~~~~~~~~~~~~~
                          bitmap_complement
