interconnect: qcom: sdm845: Enable keepalive for the MM1 BCM
[ Upstream commit 5be1805 ] After enabling interconnect scaling for display on the db845c board, in certain configurations the board hangs, while the following errors are observed on the console: Error sending AMC RPMH requests (-110) qcom_rpmh TCS Busy, retrying RPMH message send: addr=0x50000 qcom_rpmh TCS Busy, retrying RPMH message send: addr=0x50000 qcom_rpmh TCS Busy, retrying RPMH message send: addr=0x50000 ... In this specific case, the above is related to one of the sequencers being stuck, while client drivers are returning from probe and trying to disable the currently unused clock and interconnect resources. Generally we want to keep the multimedia NoC enabled like the rest of the NoCs, so let's set the keepalive flag on it too.
