[PATCH] fsl-imx6ul: Add various missing unimplemented devices

[Guenter Roeck]

Add MMDC, OCOTP, SQPI, CAAM, and USBMISC as unimplemented devices.

This allows operating systems such as Linux to run emulations such as
mcimx6ul-evk.

Before commit 0cd4926b85 ("Refactor i.MX6UL processor code"), the affected
memory ranges were covered by the unimplemented DAP device. The commit
reduced the DAP address range from 0x100000 to 4kB, and the emulation
thus no longer covered the various unimplemented devices in the affected
address range.

Fixes: 0cd4926b85 ("Refactor i.MX6UL processor code")
Cc: Jean-Christophe Dubois <jcd@tribudubois.net>
Signed-off-by: Guenter Roeck <linux@roeck-us.net>

This patch is necessary to boot mcimx6ul-evk with Linux v6.7.

My apologies for the noise if a similar patch has already been submitted
and I missed it.
