boards: renesas: smartbond: Update display settings

Browse source 
This commit should fix configuration conflicts that
came up upon merging both MIPI DBI and display panel
drivers.

1. Board's display/LVGL Kconfigs should be enabled when
   needed based on the selected display interface.
2. Overwrite the touch controller's I2C pins to avoid
   conflicts with the display panel signals.
