drm/msm/dsi/phy: Replace hardcoded char-array length with sizeof()
Now that the last DSI PHY PLL driver (dsi_phy_28nm_8960) has been
converted to use a simple stack-local char-array instead of a
devm_kzalloc heap allocation we can safely call sizeof() on every string
variable (that's now a sized array instead of a pointer) passed into
snprintf instead of hardcoding the size.
