#1352769 — [PATCH] mtd: davinci-nand: disable subpage write for davinci-nand

Commit 28c015a9daabe4e ("mtd: davinci-nand: disable subpage write for
keystone-nand") disables subpage write for Keystone SOCs due to hw
issues.

But subpage writes doesn't work even for DaVinci SOCs due to hw issues.
So set NAND_NO_SUBPAGE_WRITE option for all devices compatible to
this driver.

I tested this patch using DA850 board.
