bootcount: add a new driver with syscon as backend
The driver will use a syscon regmap as backend and supports both 16 and 32 size value. The value will be stored in the CPU's endianness. Signed-off-by: Nandor Han <nandor.han@vaisala.com> Reviewed-by: Simon Glass <sjg@chromium.org>

+ Enable reading/writing the bootcount value in a DM SYSCON device.
+ The driver supports a fixed 32 bits size register using the native

+
+ Accessing the backend is done using the regmap interface.
