Unify iMX flash config and add Metro M7 1011
This unifies the flash config to the settings used by the Boot ROM.
This makes the config unique per board which allows for changing
quad enable and status bit differences per flash device. It also
allows for timing differences due to the board layout.

This change also tweaks linker layout to leave more ram space for
the CircuitPython heap.
