Tegra changes from downstream v4

rockchip: plat_pm.c: Change callbacks implement for our SOCs.

This patch enables the SEPARATE_CODE_AND_RODATA build flag for all
Tegra platforms, to allow setting proper MMU attributes for the RO
data and the code.

The linux kernel v3.10 does not use System Suspend function ID, whereas
v4.4 uses it. This means affinity levels 0/1 will have different state id
values during System Suspend entry. This patch updates the assert criteria
to check both the state id values.

Some platforms might want to keep the uart console disabled
during boot. This patch checks if the platform supports a

is enabled. This patch updates the user-guide.md documentation for the
same.

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.

This patch modifies the secure IRQ registration process to allow platforms
to specify the target CPUs as well as the owner of the IRQ. IRQs "owned"
by the EL3 would return INTR_TYPE_EL3 whereas those owned by the Trusted
OS would return INTR_TYPE_S_EL1 as a result.

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 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.

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 adds support to relocate BL3-1 code to BL31_BASE in case
we cold boot to a different address. This is particularly useful to
maintain compatibility with legacy BL2 code.

This patch also checks to see if the image base address matches either
the TZDRAM or TZSRAM base.
