[PATCH v2 5/6] ARM: dts: stm32: Adapt STM32MP157 DK boards to stm32 DT diversity

From: Alexandre Torgue
Date: Fri Nov 29 2019 - 13:06:37 EST

To handle STM32MP15 SOCs diversity, some updates have to been done.
This commit mainly adapt dk1 board to include the correct package and the
correct SOC version. A new file has been created to factorize common parts.
