[PATCH v4,3/4] powerpc: sysdev: fix compile warning for fsl_85xx_cache_sram

[Wang Wenhu <wenhu.wang@vivo.com>]

Function instantiate_cache_sram should not be linked into the init
section for its caller mpc85xx_l2ctlr_of_probe is none-__init.

Warning information:
  MODPOST vmlinux.o
WARNING: modpost: vmlinux.o(.text+0x1e540): Section mismatch in reference from the function mpc85xx_l2ctlr_of_probe() to the function .init.text:instantiate_cache_sram()
The function mpc85xx_l2ctlr_of_probe() references
the function __init instantiate_cache_sram().
This is often because mpc85xx_l2ctlr_of_probe lacks a __init
annotation or the annotation of instantiate_cache_sram is wrong.
