kbuild: refactor some makefiles
[1] Move driver/core/, driver/input/ and drivers/input/ entries
from the top Makefile to drivers/Makefile
[2] Remove the conditional by CONFIG_DM in drivers/core/Makefile
because the whole drivers/core directory is already selected
by CONFIG_DM in the upper level
[3] Likewise for CONFIG_DM_DEMO in drivers/demo/Makefile
[4] Simplify common/Makefile - both CONFIG_DDR_SPD and
CONFIG_SPD_EEPROM are boolean macros so they can directly
select objects
