Add dma-coherent property to fastRPC context bank nodes on sm8550 and
sm8650 dtsi files to pass dma sequence test in fastrpc sanity test,
ensure that data integrity is matained during DMA operations.

Without this change, case8 and case14 about DMA sequence test in fastRPC sanity test can not pass.

The steps to do fastRPC sanity test is:
1.download code
p4 login
export PATH="$PATH:/prj/qct/asw/qctss/linux/bin/vce"
vce.py view --base fastrpctest.common.1.0 --checkout=<username> --root .
2.compile command
chmod -R 777 ./fastrpc_tests && python3 ./fastrpc_tests/build_fastrpc_test.py -target=LE
3.run fastRPC test
fastrpc_tests_ReleaseG_push_LE.bat
adb shell fastrpc_tests -e (case number) -d 3
