Bhupesh Sharma 465663e9f1 ArmPlatformPkg/TZASC: Allow specifying subregions to be disabled
ARM TZASC-380 IP provides a mechanism to split memory regions being
protected via it into eight equal-sized sub-regions. A bit-setting
allows the corresponding subregion to be disabled.

Several NXP/FSL SoCs support the TZASC-380 IP block and allow
the DDR connected via the TZASC to be partitioned into regions
having different security settings and also allow subregions
to be disabled.

This patch enables this support and can be used for SoCs which
support such a partition of DDR regions.

Details of the 'subregion_disable' register can be viewed here:
