Tim Small e97aaf483c WDR4900v1 remove dt node for absent hw crypto.
The WDR4900v1 uses the P1040 SoC, so the device tree pulls in the
definition for the related P1010 SoC.  However, the P1040 lacks the
CAAM/SEC4 hardware crypto accelerator which the P1010 device tree
defines.  If left defined, this causes the CAAM drivers (if present) to
attempt to use the non-existent device, making various crypto-related
operations (e.g. macsec and ipsec) fail.

This commit overrides the incorrect dt node definition in the included
file.
