This fix addresses a PM failure caused by an inconsistency
between the device tree and the build system. The device tree
was updated with `reg = <0x00000400 DT_SIZE_K(319)>;`,
but the corresponding value for `SL_SI91X_SI917_RAM_MEM_CONFIG`
in CMakeLists.txt was not updated, leading to the problem.
The build system now automatically sets `SL_SI91X_SI917_RAM_MEM_CONFIG`
based on the sram0 RAM size from the device tree using `dt_prop()`
and `list(GET)`, ensuring the configuration matches the device tree
and preventing future mismatches.
