refactor(st-clock): improve DT parsing for PLL nodes

Add a function to get PLL settings from DT:
"cfg" property is mandatory, an error is generated if not found.
"frac" is optional, default value is returned if not found.
"csg" is optional too, a boolean value indicates if it has been
found, and its value is updated.

Store each PLL node validity information, this avoids parsing DT
several times.

refactor(stm32mp1): remove the support of calibration result

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 CubeMX.

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 "st,phy-cal"

After this patch the built-in calibration is always executed.
