boards: renesas: ek_ra8p1: add MIPI DSI support

Add MIPI DSI support for EK-RA8P1:
- Add default configs for MEMC, GLCDC framebuffer, and LVGL
- Update DTS:
  * Add zephyr,user node with mipi-dphy-en-gpios
  * Add mipi-dsi alias and MIPI connector node
  * Add interrupts for lcdif, and mipi_dsi
  * Add aliases for lcdif, mipi_dsi, and I2C
  * Add gpio-hog for mipi_phy_enable
