disp: msm: update RSC bandwidth during solver mode transition

Browse Source 
Currently when disconnecting a secondary monitor, RSC will
transition to solver mode. If the bandwidth remains the same
for primary display, SW will not update BW indication register
causing stale TCS wait values.

This change forces a register update when RSC mode is
changed to solver mode.
