[iMX6][iMX8][SPLASH SCREEN] Fix address per CPU type
At the time, an unique address location is declared for the support of the Splash Screen. With this change, that address is set for each CPU type, inside the their common part. This fixes also the issue observed on C26: reset before the kernel boot.
