[PATCH] ARM: dts: dra7: Support QSPI MODE-0 operation at 64MHz

[Vignesh R <vigneshr-l0cyMroinI0@public.gmane.org>]

According to Data Manual(SPRS915P) of AM57x, TI QSPI controller on
DRA74(rev 1.1+) can support up to 64MHz in MODE-0, whereas MODE-3 is
limited to 48MHz. Hence, switch to MODE-0 for better throughput.
