Subject: [PATCH v2] arm64: dts: ti: k3-am62-main: Remove power-domains from
 crypto node

Only SYSFW has control of SA3UL power.
>From SYSFW 08.04.00.002, for security reasons, device ID for power
management of SA3UL has been removed.

"power-domains" property in crypto node tries to access
the SA3UL, for which it gets NACK and hence, SA3UL driver doesn't
probe properly.

Fixes: 8af893654c02 ("arm64: dts: ti: k3-am62-main: Enable crypto accelerator")
