The name of the variable holding the pointer to the private struct has
changed between Linux 5.15 and Linux 6.1 and adding the identical patch
fixing PCIe #PERST de-assert broke the build on Linux 6.1.
Also change the name in the patch to fix the build.
Fixes: 6a2e17d5c1 ("mediatek: fix PCIe #PERST being de-asserted too early")
