config/coreboot-* : adapt i915drmfb driven boards framebuffer requirements
- add additional kernel boot params for i915 where needed:
  - adds : drm_kms_helper.drm_leak_fbdev_smem=1 i915.enable_fbc=0 ( to permit kexec into vesa fb of kexec'ed kernel for i915 driven gpus without framebuffer compression, leaking smem fbdev address for kexec to pickup )
