Subject: mlxsw: acl_flex_actions: Trap all ACL dropped packets to
 DISCARD_*_ACL traps
Patch-mainline: v5.7-rc1
Git-commit: 3e6cacaf51d79ac38acf2764275d022bd61d0ef6
References: bsc#1176774

Introduce a new set of traps:
DISCARD_INGRESS_ACL and DISCARD_EGRESS_ACL
Set the trap_action from NOP to TRAP which causes the packets dropped
by the TRAP action to be trapped under new trap IDs, depending on the
ingress/egress binding point.
