To dt-fy your .config, looks like you need to add these to your build
system seed config file:

CONFIG_BACKLIGHT_CLASS_DEVICE=y
CONFIG_BACKLIGHT_GPIO=y
CONFIG_BACKLIGHT_LCD_SUPPORT=y
CONFIG_CMA=y
CONFIG_DISPLAY_PANEL_SHARP_LS037V7DW01=y
CONFIG_DMA_CMA=y
CONFIG_FRAMEBUFFER_CONSOLE_DETECT_PRIMARY=y
CONFIG_FRAMEBUFFER_CONSOLE=y
CONFIG_PINCTRL_SINGLE=y

That should actually improve your setup from the current booting
with the framebuffer enabled ;)

I also posted the defconfig and demsg for you to diff against to:

I wonder if the battery charger hardware is broken on your LDP?

I don't think that is even being enabled in the legacy boot for
LDP as it as there's no struct twl4030_bci being passed except
from board-omap3pandora.c.
