Bjarki Arge Andreasen c6cb2d6942 drivers: retained_mem: Add generic retained register driver
Devices like the ATSAM series chips have retained registers
which are used to store memory. The memory is accessed just
like RAM, but since they are registers, their size and
address is used directly.

This commit adds a near complete copy of the generic retained
ram driver and bindings file, adding the reg property to
the bindings file, and updating the init macro in the driver
to use the reg address and size.

Henrik Brix Andersen c41dd36de2 drivers: kconfig: unify menuconfig title strings
Unify the drivers/*/Kconfig menuconfig title strings to the format
"<class> [(acronym)] [bus] drivers".

Including both the full name of the driver class and an acronym makes
menuconfig more user friendly as some of the acronyms are less well-known
than others. It also improves Kconfig search, both via menuconfig and via
the generated Kconfig documentation.
