[U-Boot] [RESEND PATCH] ARM: dts: dra7x: Support QSPI MODE-0 operation at 64MHz

[Vignesh R]

According to Data Manual(SPRS915P) of AM57x, TI QSPI controller on
DRA74(rev 1.1+)/DRA72 EVM can support up to 64MHz in MODE-0, whereas
MODE-3 is limited to 48MHz. Hence, switch to MODE-0 for better
throughput.
