plat/arm: Retrieve the right ROTPK when using the dualroot CoT

The dualroot chain of trust involves 2 root-of-trust public keys:
- The classic ROTPK.
- The platform ROTPK (a.k.a. PROTPK).

Use the cookie argument as a key ID for plat_get_rotpk_info() to return the
appropriate one. This only applies if we are using the dualroot CoT ; if using
the TBBR one, the behaviour is unchanged.
