boards: arm: mimxrt1060_evk: Enable booting RT1060 from Hyperflash.

RT1060 board with hyperflash configuration was missing the appropriate
flash configuration block required by the bootloader. Since this board
uses the same flash chip as the RT1050, the flash configuration block for
that board can be reused.
