BSP package P4-ev-board

Is your feature request related to a problem?

For a game port, I need multiple framebuffers I can draw to. The LVGL version of the BSP allows me to select that, but in noglib, there is no way to get more than 1 framebuffer

Describe the solution you'd like

bsp_display_config_t could get a flag or integer field indicating multiple framebuffers are requested; bsp_display_new would need to honour that.

Describe alternatives you've considered

You can select it in menuconfig:

@espzav I don't think so. I can't really see where that option comes from in your screenshot (current bsp code only has that option in bsp/esp32_s3_lcd_ev_board/Kconfig ), and the option there is CONFIG_BSP_DISPLAY_LVGL_AVOID_TEAR=y which as the name suggests is an option that involves LVGL (and is only used here which indeed is LVGL-specific code). As mentioned before, I'm specifically using the noglib version of the BSP, which does not use LVGL and has all related code ifdef'fed out.

@Spritetm Oh sorry, it will be added in this PR: #401 and it is not merged yet. It will be merged soon (I hope today). I think that this option should be there for noglib too.
