arm64: dts: qcom: milos: Reduce rmtfs_mem size to 2.5MiB

The rmtfs_mem region is currently sized at 6MiB but the default for
milos downstream is 2.5MiB. This causes remoteproc crashes on devices
that expect the smaller size:

modem_ac.c:281:Access Control Error: Could not protect the region specified:Start:e1f00000 End:e2180000, PID:1

Reduce the default to 2.5MiB to match the QCOM downstream config, and
override the size for FP6.
