mimxrt/boards/MIMXRT1064_EVK: Fix board config to use internal flash.

iabdalkader · dpgeorge · commit 944b4c205896 · 2023-04-11T17:04:21.000+10:00
This commit is necessary to make MicroPython work on this eval kit out of
the box, as the eval kit ships with the HyperFlash physically disconnected
from the bus (refer to the schematics or the user guide) and the QSPI
connected instead, but the fuses/board/pins are configured to boot from
internal flash (on FlexSPI2).

Note that enabling the HyperFlash is not trivial, as it requires soldering
and desoldering of many small footprint resistors and changing fuses.
