pmgr: Fix false positive u8 pmgr ID detection on modern SoCs

Browse source 
The id1 field used on oder SoCs is not constant 0 for all devices on
t8122. Instead just compare the id1 fields of the two first devices.
Fixes "pmgr: Failed to find parent #36 for IOA0\n" errors in
pmgr_init().

Fixes: fb59dc03ca ("pmgr: Fix struct for older SoCs")
