    Date
    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:97:26: error: implicit declaration of function ‘ioremap_coherent’; did you mean ‘bitmap_complement’? [-Werror=implicit-function-declaration]
    cache_sram->base_virt = ioremap_coherent(cache_sram->base_phys,
    ^~~~~~~~~~~~~~~~
    bitmap_complement
    arch/powerpc/sysdev/fsl_85xx_cache_sram.c:97:24: error: assignment makes pointer from integer without a cast [-Werror=int-conversion]

    ^
