mb/google/dedede/var/drawcia: Update ext_vr for board version > 0xb
ext_vr_update should be run after board version 0xb, but skipped by
return. Drawper LTE board version was set after 0x9, but there are more
board added after that. Specific Drawper board version as 0xa, 0xb and
0xf.
BUG=b:376828839
BRANCH=firmware-dedede-13606.B
TEST=emerge-dedede coreboot chromeos-bootimage and test on DUTs.
