mtd: hyperbus: hbmc-am654: Fix direct mapping setup flash access
Setting up of direct mapping should be done with flash node's IO address space and not with controller's IO region. Fixes: b6fe8bc67d2d3 ("mtd: hyperbus: move direct mapping setup to AM654 HBMC driver") Signed-off-by: Vignesh Raghavendra <vigneshr@ti.com> Link: https://lore.kernel.org/r/20200924081214.16934-3-vigneshr@ti.com
