In pm_query_data() function return type is stored in response so
there is no use of return type. Update return type of function
pm_query_data() from enum pm_ret_status to void. Similarly
update return type of pm_api_clock_get_name() and
pm_api_pinctrl_get_function_name() functions.

- Flag GICV2_G0_FOR_EL3 needs to be set for group interrupts
  to be targeted to EL3.
- Raise SGI interrupts for individual CPU cores as GIC API
  uses CPU num as parameter, not CPU mask.
- Flag WARMBOOT_ENABLE_DCACHE_EARLY needs to be set to enable
  CPU interface mask work properly for all CPU cores which is
  required when generating SGI.
- Call plat_ic_end_of_interrupt() from ttc_fiq_handler() to clear
  GIC interrupt to avoid same interrupt again.

This API will be used to set the PLL mode: reset (unlocked), integer
or fractional (locked). If reset mode is set the PM controller will
bypass the target PLL prior to asserting the reset. If integer or
fractional mode is set the PM controller will program and trigger
locking of the PLL. If success status is returned the PLL is locked
and its bypass is deasserted. If fractional mode is set the fractional
divider (data parameter) has to have a non-zero value prior to issuing
pll set fractional mode. The caller need to ensure that the data
parameter is properly set using pll get/set parameter EEMI API.

Enforce full include path for includes. Deprecate old paths.

The following folders inside include/lib have been left unchanged:

- include/lib/cpus/${ARCH}
- include/lib/el3_runtime/${ARCH}

The reason for this change is that having a global namespace for
includes isn't a good idea. It defeats one of the advantages of having
folders and it introduces problems that are sometimes subtle (because
you may not know the header you are actually including if there are two
of them).

For example, this patch had to be created because two headers were
called the same way: e0ea0928 ("Fix gpio includes of mt8173 platform
to avoid collision."). More recently, this patch has had similar
problems: 46f9b2c3 ("drivers: add tzc380 support").

This problem was introduced in commit 4ecca339

 ("Move include and
source files to logical locations"). At that time, there weren't too
many headers so it wasn't a real issue. However, time has shown that
this creates problems.

Platforms that want to preserve the way they include headers may add the
removed paths to PLAT_INCLUDES, but this is discouraged.

ATF establishes a path to send the address of the structure
to the xilsecure, so that it will pick addresses of the data
and performs the requested operation (encrypt/decrypt) and puts
the result in load address.

where structure contains
- Data blob src address
- load address
- IV address
- Key address - this will actual key addr in case of KUP
		else it will be zero.
- Data-size
- Aes-op type

Xilinx now requires the PMU FW when using ATF, so it doesn't make sense

where ATF came up before the PMU FW (such as on QEMU) ATF will now hang
waiting for the PMU FW instead of aborting.
