We use ccflags-$(CONFIG_HWMON_DEBUG_CHIP) for the debug
message in drivers/hwmon, but the DEBUG flag will not pass to
the subdirectory.

Considering CONFIG_HWMON_DEBUG_CHIP intends to have DEBUG
recursively in driver/hwmon. It will be clearer
to use subdir-ccflags-* instead of ccflags-* to inherit
the debug settings from Kconfig when traversing subdirectories,
and it will avoid omittance of DEBUG define when debug messages
added in the subdirectories.
