disp: msm: avoid setting AMC and WAKE tage on icc vote

Setting AMC and WAKE tag triggers AMC only and WAKE+SLEEP
only vote. These dynamic tag switching is not allowed
on interconnect driver. Display SW usecases also need
ACTIVE_ONLY tag for solver enabled and disabled
configuration. ACTIVE_ONLY tag triggers AMC+SLEEP
for solver disabled and WAKE+SLEEP for solver
enabled configuration.
