[ Upstream commit b8e6d7ce50673c39514921ac61f7af00bbb58b87 ] After commit:83762cb5c7("dax: Kill DEV_DAX_PMEM_COMPAT") the pmem/ directory is not needed anymore and Makefile changes were made accordingly in this commit, but there is a Makefile and pmem.c in pmem/ which are now stale and pmem.c is empty, remove them.
