Currently ICL_PHY_MISC macro is returning offset 0x64C10 for PHY_E.
The PORT_TC1 port is not yet enabled properly in the driver, but
intel_phy_snps.c is relying on intel_phy_is_snps() to filter out
unavailable phys. That function was already considering the last phy as
available. Just correct the offset of the last phy to 0x64C14 as the
rest of the support for it is coming on next commits.
