ARM: dts: stm32: add initial support of stm32mp157c-dk2 board
Add support of stm32mp157c discovery2 board (part number: STM32MP157C-DK2). This board is a "super-set" of stm32mp157a-dk1. It embeds a STM32MP157c SOC with AC package (TFBGA361, 148 ios) and 512MB of DDR3. Same connections than stm32mp157a-dk1 board are available. Display panel (otm8009a) and Murata wifi/BT combo is added. This patch adds basic support for a kernel boot and enable otm8009a display panel. Signed-off-by: Alexandre Torgue <alexandre.torgue@st.com>
