UBUNTU: SAUCE: i915_bpo: Remove MODULE_FIRMWARE statement for i915/kbl_dmc_ver1.bin

BugLink: http://bugs.launchpad.net/bugs/1624164

This is optional firmware. It had been added to xenial's
linux-firmware but was removed due to regressions with some
hardware. Since it's not required we can remove the
MODULE_FIRMWARE statement to prevent missing firmware warnings
when generating the initrd.
