[PATCH] net: airoha: fix PCS calibration retry limit

From: Li Xiao <[email protected]>

The calibration retry counter starts at zero and is incremented after
the limit check. Using a strict greater-than comparison therefore allows
one more retry than AIROHA_PCS_MAX_CALIBRATION_TRY specifies.

Use a greater-than-or-equal comparison so the function stops after the
configured number of retries.

Fix an off-by-one condition in the Airoha AN7581 PCS calibration retry
loop. The current comparison permits one retry beyond the configured
limit.

The change was build-tested with an7581_evb_defconfig.
