mtd: eLBC NAND: fix subpage write support
commit f034d87def51f026b735d1e2877e9387011b2ba3 upstream.
As subpage write is enabled by default for all drivers, nand_write_subpage_hwecc
causes a crash if the driver did not register ecc->hwctl or ecc->calculate.
This behavior was introduced in
commit 837a6ba4f3b6d23026674e6af6b6849a4634fff9
"mtd: nand: subpage write support for hardware based ECC schemes".
This fixes a crash by emulating subpage write support by padding sub-page data
with 0xff on either sides to make it full page compatible.
