controllers to allow the device to wake the system from suspend.

Signed-off-by: bui duc phuc <phucduc.bui@gmail.com>

changes:
v4: Drop redundant "type: boolean" for wakeup-source to use the core 
    definition from dt-schema (as suggested by Rob Herring).
v3: Remove blank lines (suggested by Conor).
v2: Revise the commit content and remove patch1 related to I2C and SPI 
wakeup handling
