boards: mimxrt1170_evk: switch the default revision to B

[butok]

Switches the default revision of mimxrt1170_evk from A to B.
Customers can only purchase MIMXRT1170-EVKB.
Revision "A" is obsolete and unavailable.

PR found an error in samples/sensor/mcux_acmp.
It should be fixed by #85274

I believe you need to add a specifically named overlay file for rev B in the samples/sensor/mcux_acmp/boards/

I would do a global scan for any others.

As documented, the Rev. B does not support ACMP: https://docs.zephyrproject.org/latest/boards/nxp/mimxrt1170_evk/doc/index.html#supported-features

Hm. Strange behavior of CI: https://github.com/zephyrproject-rtos/zephyr/actions/runs/13239076808/job/36950204779?pr=85233
unrecognized platform - mimxrt1170_evk@A/mimxrt1176/cm7
But I am able to be build locally : west build -p always -b mimxrt1170_evk@A/mimxrt1176/cm7 samples/sensor/mcux_acmp
