Re: [U-Boot] [PATCH 08/11] dm: video: Don't do anything in alloc_fb() when plat->size is zero

With DM VESA driver on x86 boards, plat->base/size/align are all zeroes and starting address passed to alloc_fb() happens to be 1MB aligned, so this routine does not trigger any issue. On QEMU with U-Boot as coreboot payload, the starting address is within 1MB range (eg: 0x7fb0000), thus causes failure in video_post_bind().

Actually if plat->size is zero, it makes no sense to do anything in this routine. Add such check there.
