rockchip: video: Kconfig: set MAX_XRES and MAX_YRES via Kconfig
This introduces two new Kconfig options that configure the maximum
allowable framebuffer size (i.e. the memory reservation/allocation for
the framebuffer):
- VIDEO_ROCKCHIP_MAX_XRES
- VIDEO_ROCKCHIP_MAX_YRES
The resulting memory allocation will cover 4 byte per pixel for these
resolutions.
