The GIC area is specified larger than it needs to be and can be reduced.
Which allows reducing the structures required for the translation tables
as well.
This results in a reduction of memory footprint of ca. 4k.

Drop the current configuration options for selecting the location of
the ATF and TSP (ZYNQMP_ATF_LOCATION, ZYNQMP_TSP_RAM_LOCATION).
The new configuration provides one default setup (ATF in OCM,
BL32 in DRAM). Additionally, the new configuration options
 - ZYNQMP_ATF_MEM_BASE
 - ZYNQMP_ATF_MEM_SIZE
 - ZYNQMP_BL32_MEM_BASE
 - ZYNQMP_BL32_MEM_SIZE
can be used to freely configure the memory locations used for ATF and
secure payload.

Also, allow setting the BL33 entry point via PRELOADED_BL33_BASE.
