drivers: hci: da1469x: Add driver for CMAC core on DA1469x

This adds HCI driver which enables communication with CMAC core on Renesas SmartBond DA1469x series. The CMAC core is running an Apache NimBLE controller binary and uses shared memory for communcation via mailboxes. The protocol over mailboxes is H4 so the code is based on existing hci_h4 driver.
