[PATCH 0/2] Add a build time parameter to accept custom signing key

[T Pratham]

This series adds support to use a custom key provided via Make during
build for signing the bootloader binaries, and updates the k3-binman to
use it. 

This parameter is optional and not using it will simply cause the build
to fallback to the key provided in the filename property (e.g the
example keys in arch/arm/mach-k3/keys/custMpk.pem for k3 SoCs) for
signing. Any existing methods for replacing the example keys stil remain
same and can be used. For supplying a key at build, the full path to the
key file needs to be provided while running make to the parameter
SIGNING_KEY:

make SIGNING_KEY=<path to a key> [other make options]
