In below call trace:
mmc_rescan
-> mmc_rescan_try_freq()
-> mmc_attach_sdio()
-> mmc_sdio_init_card()
...
pm_runtime_set_active()
...
mmc_add_card()
The dev name is set until in mmc_add_card(), but before that, it is
possible the dev name is needed, for example in pm_runtime_set_active(),
we can call trace event to trace which dev is changing the runtime status.
So here advance it into mmc_sdio_init_card() to benefit others.
