[PATCH v2] Kconfig: Don't use RSA_FREESCALE_EXP on MX7ULP

[PATCH v2] Kconfig: Don't use RSA_FREESCALE_EXP on MX7ULP

[Oleksandr Suvorov]

From: Ricardo Salveti <ricardo@foundries.io>

The CAAM on IMX7ULP doesn't support public key hardware acceleration
(PKHA), as in other NXP parts. Disable RSA_FREESCALE_EXP for IMX7ULP
too.

Fixed: f4e9ff7135 ("Kconfig: Don't use RSA_FREESCALE_EXP on IMX")
Signed-off-by: Ricardo Salveti <ricardo@foundries.io>

Changes in v2:
- add a dependency rule for RSA_FREESCALE_EXP
