mfd: db5500-prcmu: add modem_req and modem_rel API
When APE has some messages to send to modem, APE will issue a modem_req
and then start sending the messages to modem.
Once APE is done with sending messages to modem, it will send modem_rel
to free the ape-modem communication protocol.
This protocol will be used to achieve APE-Modem power management.
