drm/msm/dsi: Get rid of msm_dsi_config::num_dsi

Browse Source 
In preparation for supporting multiple sets of possible base registers,
remove the num_dsi variable. We're comparing the io_start array contents
with the reg value from the DTS, so it will either match one of the
expected values or don't match against a zero (which we get from partial
array initialization).
