This commit introduces fix for PureEdDSA signature verification when the flash base address is not 0x0. The issue was that the flash base address was not taken into account when passing the image address to the signature verification function.

Additionally, FLASH_DEVICE_ID for nRF54H20 platform was corrected.

Upstream PR #:2414
