clk: msm: clock-gcc-8998: keep gcc_bimc_gfx_clk on 



Keep gcc_bimc_gfx_clk always on to prevent a stall during BIMC
redirection handshake that occurs as part of a transition between
different CCI power modes. The stall causes momentary bandwidth drops
for the display ports and creates display buffer underflows.
