Subject: [PATCH] soc: qcom: Select REMAP_MMIO for ICC_BWMON driver

ICC_BWMON 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/icc-bwmon.ko] undefined!
make[1]: *** [scripts/Makefile.modpost:126: Module.symvers] Error 1
make: *** [Makefile:1944: modpost] Error 2
