This commit removes the flexram,bank-spec property from dtsi files.
The property causes flexram to be dynamically configured based on
the configuration in flexram,bank-spec. This is a problem for 2 reasons:
1) The FlexRAM will always be dynamically reconfigured to default
fuse configuration. This is unnecessary if using default fuses.
2) If a user decides to program fuses. The FlexRAM will still be
reconfigured to the default fuse configuration.
Modify description in the binding to show how to use the property at:
dts/bindings/memory-controllers/nxp,flexram.yaml
