[PATCH] ARM: dts: stm32: disable SYSRAM SCMI shared memory in stm32mp15-scmi

[Patrice Chotard]

Changes scmi node to not use a statically defined sram shared memory
buffer. This change makes SCMI OP-TEE transport to use shared memory
allocated used OP-TEE generic shared memory resources.

Removes the sram definition in the DTSI files since no more used.
