When CONFIG_MUX_MMIO and CONFIG_HBMC_AM654 are both 'm', there are
some building error as below:
drivers/mux/mmio.c: In function mux_mmio_probe:
drivers/mux/mmio.c:76:20: error: storage size of field isnt known
struct reg_field field;
^~~~~
drivers/mux/mmio.c:102:15: error: implicit declaration of function devm_regmap_field_alloc; did you mean devm_mux_chip_alloc? [-Werror=implicit-function-declaration]
fields[i] = devm_regmap_field_alloc(dev, regmap, field);
^~~~~~~~~~~~~~~~~~~~~~~
devm_mux_chip_alloc
drivers/mux/mmio.c:76:20: warning: unused variable field [-Wunused-variable]
struct reg_field field;
^~~~~
cc1: some warnings being treated as errors
make[2]: *** [drivers/mux/mmio.o] Error 1
make[1]: *** [drivers/mux] Error 2
make[1]: *** Waiting for unfinished jobs....
make: *** [drivers] Error 2
This because CONFIG_REGMAP is not enable, so change the Kconfig for HBMC_AM654.
