Drop Mellanox FPGA IPsec support from the kernel

From: Leon Romanovsky <[email protected]>

Together with FPGA TLS, the IPsec went to EOL state in the November of 2019 [1]. Exactly like FPGA TLS, no active customers exist for this upstream code and all the complexity around that area can be deleted.

Thanks
