[PATCH u-boot v2019.04-aspeed-openbmc] tools: Disable OpenSSL deprecation warnings

[Joel Stanley]

mkimage is linked against the host version of OpenSSL. If the distro
happens to be using OpenSSL 3.0 then several warnings about using
depreciated functions will be emitted.

 warning: ‘RSA_get0_key’ is deprecated: Since OpenSSL 3.0 [-Wdeprecated-declarations]

These functions still work for now, so suppress the warning and delay
the need to move to the new API.

The backport to move to the newer OpenSSL APIs are complicated. Instead
of focusing on fixing the old branch, work is being done to move to a
newer u-boot base.
