dts: arm: nxp: RT10xx/11xx .dtsi Files: Remove flexram,bank-spec property 

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

Added board overlay to mimxrt1170_evk_cm7 magic_addr:

NXP FlexRAM on-chip ram controller
If the flexram,bank-spec property is specified, then the flexram will be
dynamically reconfigured to the configuration specified at runtime. An
example to configure the flexram dynamically using the
flexram,bank-spec property for rt1060 is as follows:
&itcm {
reg = < 0x0 DT_SIZE_K(64) >;
};
&dtcm {
reg = < 0x20000000 DT_SIZE_K(384) >;
};
&ocram {
reg = < 0x20280000 DT_SIZE_K(64) >;
};
&flexram {
flexram,bank-spec = <FLEXRAM_OCRAM>,
<FLEXRAM_OCRAM>,
<FLEXRAM_DTCM>,
<FLEXRAM_DTCM>,
<FLEXRAM_DTCM>,
<FLEXRAM_DTCM>,
<FLEXRAM_DTCM>,
<FLEXRAM_DTCM>,
<FLEXRAM_ITCM>,
<FLEXRAM_ITCM>,
<FLEXRAM_DTCM>,
<FLEXRAM_DTCM>,
<FLEXRAM_DTCM>,
<FLEXRAM_DTCM>,
<FLEXRAM_DTCM>,
<FLEXRAM_DTCM>;
};
This will configure the flexram for 384K of DTCM, 64K of ITCM,
and 64K of OCRAM.
