- Fix rk3288 tinker and evb SPL boot fail
- Enable get sn from cpuid for rk3399 rockpro64 board

- Coding style corrections in some RTC drivers.
- Small doc updates.
- Regression fix in part_test_dos()
- Regression fix on TI OMAP WDTs.
- Document deadline for CONFIG_DM migration.
- Switch Travis-CI to "xenial" release.

For many sub-systems we already require the driver model to be used. Yet
there is still a handful of boards that do not have CONFIG_DM enabled.

We should make CONFIG_DM compulsory with release v2020.01

Conversion dates for CONFIG_DM_SPL and CONFIG_DM_TPL are yet to be defined.

SPL sets up SDRAM while in its board_init_f()
function, it is possible for the stack to move
there before board_init_r() is reached.

So it is required to reserve the stack for SDRAM,
with a proper location and size otherwise any
operations during SPL handoff would leads to failure.

On, this particular context tinker-rk3288 SPL is
failing to launch U-Boot proper on SDRAM due to
lack of stack.

Few of the rk3288 boards like tinker, vyasa are using
