Per updated Reference Mannual, the TPM[1,3] LPIT[1,2] root clock entries
are reserved, it is because writing the CCM registers does nothing
because the TPM[1,3] and LPIT[1,2] IPs source from bus clk, not from the
TPM[1,3] LPIT[1,2] entries. And because there is no SW entity is using the
entries since adding them, let's drop them.
