Enable an existing simple framebuffer node in the Linux kernel device
tree and the add the associated reserved memory node to preserved the
resources (clock, memory) used by the stm32 video driver to display
the splashscreen = background in exlinux.conf file.
These resources will be released by the Linux driver only when the
associated driver is ready to avoid transition issues during the Linux

The support of a predefined DDR PHY tuning result is removed for
STM32MP1 driver because it is not needed at the supported frequency
when built-in calibration is executed.
The calibration parameters were provided in the device tree by the
optional node "st,phy-cal", activated in ddr helper file by the
compilation flag DDR_PHY_CAL_SKIP and filled with values generated
by the CubeMX DDR utilities.
This patch
- updates the binding file to remove "st,phy-cal" support
- updates the device trees and remove the associated defines
- simplifies the STM32MP1 DDR driver and remove the support of
the optional parameter "st,phy-cal"
After this patch, the built-in calibration is always executed
and the calibration registers are moved in the phy dynamic part;
that allows manual tests.

Add support for testing whether bus voltage level translator is present
and operational. This is useful on systems where the bus voltage level
translator is optional, as the translator can be auto-detected by the
driver and the feedback clock functionality can be disabled if it is
not present.
The translator test sets CMD high to avoid interfering with a card, and
then verifies whether signal set on CK is detected on CKIN. If the signal
is detected, translator is present, otherwise the CKIN feedback clock are
disabled.

At present the collection function used by pytest is quite strict on the
naming of the functions it detects. In particular it requires the name of
the test to be repeated in the function name.
This is not enforced anywhere else, but instead the tests are silently
omitted from the pytest run. This affects a few dozen tests.
The rule does not seem to have any particular purpose. Relax it, so that
all tests that use the UNIT_TEST() macro will run, regardless of the name
of the test function.
