plat/arm/rddanielxlr: add platform function to return ROTPK

TBBR authentication framework depends on the plat_get_rotpk_info()
function to return the pointer to the Root of Trust Public Key (ROTPK)
stored in the platform along with its length. Add this function for
RD-Daniel Config-XLR platform to support Trusted Board Boot. The
function makes use of the wrapper function provided by the arm common
trusted board boot function to get the ROTPK hash.
