timeout.

The vcu disable bit in efuse ipdisable register is valid
only if PL powered up so, consider PL powerup status for
determing EG/EV part. If PL is not powered up, display
EG/EV as a part of string. The PL powerup status will
be filled by pmufw based on PL PROGB status in the
9th bit of version field.This patch also used IPI
to get this info from pmufw instead of directly accessing
the registers. Accessing this info from pmufw using
IPI fixes the issue of PMUFW access denied error for
reading IPDISABLE register.

Read ipdisable reg which needs to be used for cg/eg/ev device detection.
ATF runs in EL3 that's why this read can be done directly.

On ZynqMP the FSBL will configure the system counter. Hence, remove the
initialization of the system counter with hardcoded values from the ATF
and use the setup provided by the bootloader.

Arm provided error injection support. To enable this error injection,
we need to set L2DEIEN in L2ACTLR_EL1 register and L1DEIEN in
CPUACTLR_EL1 register.

This is needed for our cortexa53 edac linux driver testing.
These registers need write access from non secure EL1 i.e linux
at the time of setting the above bits.

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.
