qcs404: sysmap: Don't map reserved memory ranges

Currently u-boot maps whole of 1G RAM but there reserved memory ranges on
QCS404 which are reserved for TrustZone, various firmware components etc.
Any access to these reserved memory ranges causes a bus hang issue. So
disable mapping for reserved memory ranges in u-boot.
