[PATCH 5/7] PCI: apple: Drop poll for CORE_RC_PHYIF_STAT_REFCLK
From: Alyssa Rosenzweig
Date: Tue Feb 11 2025 - 14:56:08 EST
From: Hector Martin <marcan@xxxxxxxxx>
This is checking a core refclk in per-port setup which doesn't make a
lot of sense, and the bootloader needs to have gone through this anyway.
It doesn't work on T602x, so just drop it across the board.
