Description

### Description

These tests break with the integration of the `keymgr_dpe` and the `rram` into `earlgrey`.

## Reason `keymgr_dpe`:

With `SECRET2` pre-locked in the OTP image, `keymgr_dpe_testutils.c:296-306` cannot provision the
creator seed flash page, so the HW seed read of that zero-filled page errors on every
boot and latches a sticky `FLASH_CTRL.FAULT_STATUS` bit. `flash_exc_handler` requires `FAULT_STATUS` to
read back exactly zero, so it stops absorbing real ECC faults and shuts down instead.

## Reason `rram`:
