Move plat/common source file definitions to generic Makefiles
These source file definitions should be defined in generic Makefiles so that all platforms can benefit. Ensure that the symbols are properly marked as weak so they can be overridden by platforms.
NOTE: This change is a potential compatibility break for non-upstream platforms.

This patch implements a per-soc handler to calculate the target power state for the cluster/system. A weak implementation of the handler is provided for platforms to use by default.
For SoCs with multiple CPU clusters, this handler would provide the individual cluster/system state, allowing the PSCI service to flush caches during cluster/system power down.

Tegra: implement FIQ interrupt handler
This patch adds a handler for FIQ interrupts triggered when the CPU is in the NS world. The handler stores the NS world's context along with ELR_EL3/SPSR_EL3.
The NS world driver issues an SMC initially to register it's handler. The monitor firmware stores this handler address and jumps to it when the FIQ interrupt fires. Upon entry into the NS world the driver then issues another SMC to get the CPU context when the FIQ fired. This allows the NS world driver to determine the CPU state and call stack when the interrupt fired. Generally, systems register watchdog interrupts as FIQs which are then used to get the CPU state during hangs/crashes.

Tegra: GIC: enable FIQ interrupt handling
Tegra chips support multiple FIQ interrupt sources. These interrupts are enabled in the GICD/GICC interfaces by the tegra_gic driver. A new FIQ handler would be added in a subsequent change which can be registered by the platform code.
This patch adds the GIC programming as part of the tegra_gic_setup() which now takes an array of all the FIQ interrupts to be enabled for the platform. The Tegra132 and Tegra210 platforms right now do not register for any FIQ interrupts themselves, but will definitely use this support in the future.

Tegra: implement common handler `plat_get_target_pwr_state()`
This patch adds a platform handler to calculate the proper target power level at the specified affinity level.
Tegra platforms assign a local state value in order of decreasing depth of the power state i.e. for two power states X & Y, if X < Y then X represents a shallower power state than Y. As a result, the coordinated target local power state for a power domain will be the maximum of the requested local power state values.

This patch maps the TZDRAM carveout used by the BL31. In the near future BL31 would be running from the TZRAM for security and performance reasons.
