[PATCH 5.7 311/393] mtd: rawnand: brcmnand: Dont default to edu transfer

[Greg Kroah-Hartman]

From: Kamal Dasu <kdasu.kdev@xxxxxxxxx>

[ Upstream commit bee3ab8bdd3b13faf08e5b6e0218f59b0a49fcc3 ]

When flash-dma is absent do not default to using flash-edu.
Make sure flash-edu is enabled before setting EDU transfer
function.

Fixes: a5d53ad26a8b ("mtd: rawnand: brcmnand: Add support for flash-edu for dma transfers")
