[PATCH v2 4/6] mach-k3: security: Propagate verified image addr

[Philippe Schenker]

From: Philippe Schenker <philippe.schenker at impulsing.ch>

The ti_secure_image_check() function may relocate the image during
authentication, updating image_addr to point to the verified location.
The caller was not updated with this new address, causing it to
reference the original unverified location.

Update p_image with the verified image address after authentication
to ensure subsequent operations use the correct location.

Changes in v2:
- Fixed pointer cast warning by using uintptr_t intermediate cast. The
  direct cast from u64 to pointer caused a -Wint-to-pointer-cast warning
  on 32-bit ARM R5 targets. Using (uintptr_t) as intermediate cast is
  safer and architecture-aware, ensuring proper handling on both 32-bit
  and 64-bit targets.
