[Patch RESEND 4/4] memory: tegra: make icc_set_bw return zero if BWMGR not supported

Return zero from icc_set_bw() to MC client driver if MRQ_BWMGR_INT
is not supported by the BPMP-FW. Currently, 'EINVAL' is returned
which causes error message in client drivers even when the platform
doesn't support scaling.
