ARM: dts: am437x-idk: Fix QSPI compatible string

Unlike Linux kernel, U-Boot depends on "spi-flash" compatible to probe
m25p80 spi-nor devices. Hence, add "spi-flash" compatible string to
m25p80 node. Without this patch, flash device DT data is not parsed and
QSPI operates in unsupported mode leading to data corruption.
