Virtually all PCs nowadays have a PCI bridge and PCI devices.
All framnebuffer options depend on CONFIG_FB, which default is not 'y',
so also enable that.
The overwhelming majority of PCs nowadays also come with an UEFI
bootloader, that configures a framebuffer usable in early boot, which
the kernel can reuse without needing any hardware-specific driver.
EDID allows retrieving the capabilities of the connected display,
especially the frequencies and so on, to properly drive the display.

The default ORC unwinder requires libelf to be built. While we could
build libelf using BR2_LINUX_KERNEL_NEEDS_HOST_LIBELF, we probably
don't really need the ORC unwinder in the PC defconfigs, so let's use
the frame pointer unwinder instead.

Reusing the qemu x86-64 linux config isn't very obvious, so these defconfigs
aren't taken into consideration when the qemu defconfigs are updated,
breaking the build.
Instead use a custom linux config for the pc defconfigs. With this, we also
can get rid of the fragment file containing the delta fra the qemu config.
Created by linux-update-defconfig (after turning of the fragment file).
Also drop the linux kernel version number from the file name as it just
causes extra noise whenever the kernel is bumped.
