drm: msm: mdp4: Adjust indentation in mdp4_dsi_encoder_enable

commit 251e3cb1418ff3f5061ee31335e346e852b16573 upstream.

Clang warns:

../drivers/gpu/drm/msm/disp/mdp4/mdp4_dsi_encoder.c:124:3: warning:
misleading indentation; statement is not part of the previous 'if'
[-Wmisleading-indentation]
         mdp4_crtc_set_config(encoder->crtc,
         ^
../drivers/gpu/drm/msm/disp/mdp4/mdp4_dsi_encoder.c:121:2: note:
previous statement is here
        if (mdp4_dsi_encoder->enabled)
        ^

This warning occurs because there is a space after the tab on this line.
Remove it so that the indentation is consistent with the Linux kernel
coding style and clang no longer warns.
