Since we added clk enable_count and prograte clk child enabling
operation to clk parent, so add a new function sandbox_clk_enable_count
to get enable_count for test usage.

And add test code to get the enable_count after we enable/disable
the device clk.

- More DaVinci updates and fixes
- PCIe support on am65x
- Watchdog converted to DM
- Assorted other bugfixes

Current dev_read_*() API lacks support to get address and size
of a "reg" property by name or index. Add support for the same.

Livetree support has been added but not tested on real hardware.

The existing unit tests testing reading address from device-tree
have been updated to test address as well as size.

Add support for clk_is_match() which is required to
know if two clock pointers point to the same exact
physical clock.

Also add a unit test for the new API.

- CCF for i.MX6
- nandbcb command to write SPL into NAND
- Switch to DM (i.MX28)
- Boards: Toradex, engicam, DH
- Fixes for i.MX8
- Fixes for i.MX7ULP

Travis: https://travis-ci.org/sbabic/u-boot-imx/builds/561147504

- add rtc driver for stm32mp1
- add remoteproc driver for stm32mp1
- use kernel qspi compatible string for stm32

The current implementation supports only binary file load.
Add helpers to support ELF32 format (sanity check, and load).
Note that since an ELF32 image is built for the remote processor, the
load function uses the device_to_virt ops to translate the addresses.
Implement a basic translation for sandbox_testproc.

Add related tests. Test result:
=> ut dm remoteproc_elf
Test: dm_test_remoteproc_elf: remoteproc.c
Test: dm_test_remoteproc_elf: remoteproc.c (flat tree)
