cmd: zynqrsa: Dont use ppk info from image

This patch removes usage of PPK info from image as it
is supposed to use the verified key residing in OCM for
verificationof SPK. u-boot is already reading PPK data
from OCM, so removing the code of reading from image should
be sufficient. The PPK was actually verified and placed in
OCM by bootrom during boot.
