Subject: [PATCH 1/3] ARM: dts: stm32: add CRC on stm32mp131

From: Lionel Debieve <lionel.debieve@...s.st.com>

The Cyclic redundancy check calculation unit (CRC) peripheral
offers a CRC-based operation (CRC32/CRC32C) used to verify data
transmission or storage integrity.
This peripheral is integrated in stm32mp131 and can be default
enabled.
