Since commit 5bc6f8c2a97e("video: stm32: remove test on CONFIG_DM_REGULATOR")
backlight was broken with the following message at boot:
stm32-display-dsi dsi@40016c00: Warning: cannot get phy dsi supply
stm32_display display-controller@40016800: panel panel enable backlight error
-38
DM_REGULATOR flag must be enabled to fix this issue
