drm/i915/cx0_phy: Fix ARL-S host bridge detection
Fix is_arrowlake_s_by_host_bridge() which always returned false.
The while loop always exits with pdev as NULL, so the return
condition was always false, causing the wrong tx_misc value to be used.
Check the host bridge ID inside the loop body. Once found early exit
from the loop release the pci reference "pdev" and return true.
