From: Manivannan Sadhasivam <manivannan.sadhasivam@xxxxxxxxxx>
commit 5d2fe2d7b616b8baa18348ead857b504fc2de336 upstream.
LLCC driver uses REGMAP_MMIO for accessing the hardware registers. So
select the dependency in Kconfig. Without this, there will be errors
while building the driver with COMPILE_TEST only:
ERROR: modpost: "__devm_regmap_init_mmio_clk" [drivers/soc/qcom/llcc-qcom.ko] undefined!
make[1]: *** [scripts/Makefile.modpost:126: Module.symvers] Error 1
make: *** [Makefile:1944: modpost] Error 2
