Allow qemu users to enable stack protection. Since the virt platform
does not provide an RNG, use a basic, timer-based, canary generation,
similarly to FVP.
Increase SRAM size and BL2 size to fit images when stack protection is
enabled.
Notice that stack protection is not enabled by default in qemu.

there are two fix for save/restore watchdog register:
1. watchdog plck will shutdown after secure_watchdog_disable(), so need
to save register before it and restore after secure_watchdog_enable().
2. need write 0x76 to cnt_restart to keep watchdog alive when restore
watchdog register.

x3 will be assigned by the folloing instructions.
So the first instruction is not needed any more.
old method:
(ClusterId * FVP_MAX_CPUS_PER_CLUSTER)
+ (CPUId * FVP_MAX_PE_PER_CPU)
+ ThreadId
it should be
(ClusterId * FVP_MAX_CPUS_PER_CLUSTER) * FVP_MAX_PE_PER_CPU
+ (CPUId * FVP_MAX_PE_PER_CPU)
+ ThreadId
which can be simplified as:
(ClusterId * FVP_MAX_CPUS_PER_CLUSTER + CPUId) * FVP_MAX_PE_PER_CPU + ThreadId

Existing database allows to set only single mode for SDIO.
SDIO can have different groups (8 bit, 4 bit and 1 bit).
As there is only single SDIO group in each pin, it is not
possible to use different mode groups for SDIO.
Extend database in generic way to allow multiuple function
groups in single pin. Add different SDIO groups to pins and
create separate functions for each modes.

Add pin control APIs which driver can use to query
pin information from firmware. Using these APIs,
driver do not need to maintain hard-coded pin database.
Major changes in patch are:
- Add pin database with pins, functions and function groups
information
- Implement APIs for pin information queries
- Update pin control APIs for get/set functions to use new
pin control database. Remove pin database which was added
earlier.

Boot memory layout is specific for a platform, but should not be
mixed up with other platform specific attributes. A separate file is
much cleaner and better to compare with other platforms. Take a look
at plat/poplar where it is done the same way.

hikey_def.h to more general platform_def.h.

Previously, Juno used to depend on the SSC_GPRETN register to inform
about the reset syndrome. This method was removed when SCP migrated
to the SDS framework. But even the SDS framework doesn't report the
reset syndrome correctly and hence Juno failed to enter Firmware
update mode if BL2 authentication failed.
In addition to that, the error code populated in V2M_SYS_NVFLAGS register
does not seem to be retained any more on Juno across resets. This could
be down to the motherboard firmware not doing the necessary to preserve
the value.
Hence this patch modifies the Juno platform to use the same mechanism to
trigger firmware update as FVP which is to corrupt the FIP TOC on
authentication failure. The implementation in `fvp_err.c` is made common
for ARM platforms and is moved to the new `arm_err.c` file in
plat/arm/common folder. The BL1 and BL2 mmap table entries for Juno
are modified to allow write to the Flash memory address.

This issue was detected when testing FWU on Juno. The Timer
`timer_ops` was not being initialized before being used by
the SDS driver on Juno. This patch adds the call to
`generic_delay_timer_init()` during bl2u_early_platform_setup().
This is done generically for all ARM platforms because the
cost involved is minimal.
