Paras Sharma c9ca43d42e serial: qcom_geni_serial: To correct QUP Version detection logic
For QUP IP versions 2.5 and above the oversampling rate is
halved from 32 to 16.

Commit ce73460054 ("tty: serial: qcom_geni_serial: Update
the oversampling rate") is pushed to handle this scenario.
But the existing logic is failing to classify QUP Version 3.0
into the correct group ( 2.5 and above).

As result Serial Engine clocks are not configured properly for
baud rate and garbage data is sampled to FIFOs from the line.

So, fix the logic to detect QUP with versions 2.5 and above.

Fixes: ce73460054 ("tty: serial: qcom_geni_serial: Update the oversampling rate")
