This series of patches extends the way how pblk can
store L2P sector metadata. After this set of changes
any size of NVMe metadata is supported in pblk.
Also there is an support for case without NVMe metadata.
Changes v3 --> v4:
-rename nvm_alloc_dma_pool() to nvm_create_dma_pool()
-split pblk_get_meta() calls and lba setting into
two operations for better core readability
-fixing compilation with CONFIG_NVM disabled
-getting rid of unnecessary memcpy for packed metadata
on write path
-support for drives with oob size >0 and <16B in packed
metadata mode
-minor commit message updates
Changes v2 --> v3:
-Rebase on top of ocssd/for-4.21/core
-get/set_meta_lba helpers were removed
-dma reallocation was replaced with single allocation
-oob metadata size was added to pblk structure
-proper checks on pblk creation were added
Changes v1 --> v2:
-Revert sector meta size back to 16b for pblk
-Dma pool for larger oob meta are handled in core instead of pblk
-Pblk oob meta helpers uses __le64 as input outpu instead of u64
-Other minor fixes based on v1 patch review

Igor,
I pushed the preparation patch to core. Please rebase and I'll pick up
the patches.
Thank you.
