Fixes gcc '-Wunused-but-set-variable' warning:
drivers/gpu/drm/msm/dsi/phy/dsi_phy.c: In function msm_dsi_dphy_timing_calc_v2: drivers/gpu/drm/msm/dsi/phy/dsi_phy.c:156:17: warning: variable lpx set but not used [-Wunused-but-set-variable] drivers/gpu/drm/msm/dsi/phy/dsi_phy.c: In function msm_dsi_dphy_timing_calc_v3: drivers/gpu/drm/msm/dsi/phy/dsi_phy.c:273:17: warning: variable lpx set but not used [-Wunused-but-set-variable]
'lpx' in msm_dsi_dphy_timing_calc_v2 is not used since commit a4df68fa232e ("drm/msm/dsi: Add new method to calculate 14nm PHY timings")
'lpx' in msm_dsi_dphy_timing_calc_v3 is not used since commit f1fa7ff44056 ("drm/msm/dsi: implement auto PHY timing calculator for 10nm PHY")
