clk: imx: imx8ulp: Add tpm5 clock as critical gate clock

The TPM5 is used for broadcast timer purpose and registered
with TIMER_OF_DECLARE. As the clock driver is not ready at
that stage, so the TPM5 clock is configured in bootloader(TF-A).
if we just remove the TPM5 clock from linux will introduce a
risk that the TPM5's parent clock will be gated, then lead to
TPM's channel control config can NOT be written into register
successfully.

Due to the above reason, we still need to add the TPM5 clock
into linux clock but register it as a simple critical gate
clock to make sure its parent is always on.
