mb/google/poppy/variants/nocturne: remove icc_max overrides

Remove icc_max overrides to allow SoC code to set proper
icc_max based on CPU SKU.

BUG=b:78122599
BRANCH=none
TEST='emerge-nocturne coreboot chromeos-bootimage', flash to
nocturne, boot to kernel and verify device doesn't hang after
a few minutes.
