Subject: [PATCH 1/7] drivers: qcom: rpmh-rsc: fix the loop index check in get_req_from_tcs

From: "Raju P.L.S.S.S.N" <rplsssn@...eaurora.org>

get_req_from_tcs introduced in patch[1] returns tcs_request from
tcs_group. The size of tcs (of type - tcs_group) array in rsc_drv is
TCS_TYPE_NR. So the loop index needs to be iterated up to TCS_TYPE_NR only.
