This parameter "st,phy-cal" becomes optional and when it is absent the built-in
PHY calibration is done.
It is the case in the helper dtsi file "stm32mp15-ddr.dtsi"
except if DDR_PHY_CAL_SKIP is defined.
This patch also impact the ddr interactive mode

the registers of the param 'phy.cal' are initialized to 0 when
"st,phy-cal" is not present in device tree (default behavior when
DDR_PHY_CAL_SKIP is not activated)
the info 'cal' field can be use to change the calibration behavior
cal=1 => use param phy.cal to initialize the PHY, built-in training
         is skipped
cal=0 => param phy.cal is absent, built-in training is used (default)
