Subject: undefined reference to `mmc_pm_notify' when selected MMC without PM.

Hi,

Following is build error when selected MMC without PM.

drivers/built-in.o: In function `mmc_alloc_host':
drivers/mmc/core/host.c:108: undefined reference to `mmc_pm_notify'
make[1]: *** [.tmp_vmlinux1] Error 1
make: *** [sub-make] Error 2

That is added from Maxim's ' mmc: fix all hangs related to mmc/sd card
insert/removal during suspend/resume '
(commit ID: 4c2ef25fe0b847d2ae818f74758ddb0be1c27d8e)

Below is temporary patch for avoiding build error.
But I'm not sure about this... :-(

Thanks.
