mtd: rawnand: fsl_elbc: Remove NAND_NO_SUBPAGE_WRITE flag

Browse Source 
Subpage write support for freescale eLBC NAND controller driver is
implemented in U-Boot and was fixes in the commit d3963721d93f ("nand: Sync
with Linux v4.1").

So remove NAND_NO_SUBPAGE_WRITE flag from the fsl_elbc_nand.c driver. This
partially revert commit cb04c7723429 ("nand/fsl: add NAND_NO_SUBPAGE_WRITE
to eLBC and IFC drivers"), only eLBC driver part.

With this change U-Boot with default settings can read from NAND UBIFS
image created on Linux with Linux default settings. Prior this change
U-Boot was unable to read from NAND UBIFS images created with Linux default
settings due to differnet UBI geometry.

Linux kernel fsl_elbc_nand.c driver also does not set NAND_NO_SUBPAGE_WRITE
flag and has implemented subpage write support.

Fixes: cb04c7723429 ("nand/fsl: add NAND_NO_SUBPAGE_WRITE to eLBC and IFC drivers")
Fixes: d3963721d93f ("nand: Sync with Linux v4.1")
