From: Arnd Bergmann <arnd@arndb.de>

Selecting this without CONFIG_BLK_DEV causes a Kconfig warning:

WARNING: unmet direct dependencies detected for LIBNVDIMM
  Depends on [n]: PHYS_ADDR_T_64BIT [=y] && HAS_IOMEM [=y] && BLK_DEV [=n]
  Selected by [y]:
  - BCACHE_NVM_PAGES [=y] && MD [=y] && BCACHE [=y] && PHYS_ADDR_T_64BIT [=y]

Add it as another dependency.

Fixes: 688330711e9a ("bcache: initialize the nvm pages allocator")
