Simon Glass 336d4615f8 dm: core: Create a new header file for 'compat' features 
At present dm/device.h includes the linux-compatible features. This
requires including linux/compat.h which in turn includes a lot of headers.
One of these is malloc.h which we thus end up including in every file in
U-Boot. Apart from the inefficiency of this, it is problematic for sandbox
which needs to use the system malloc() in some files.

Move the compatibility features into a separate header file.

Han Nandor 0b326fc296 rtc: add support for DS3232 device 
DS3232 is an i2c RTC with 236 bytes of battery-backed SRAM.

Add an RTC driver for DS3232 device, which provides time and
date support. Also read and write functions are provided,
which can be used to access the SRAM memory.
