Tegra: dummy support for the io_storage backend

This patch provides dummy macros and platform files to compile
the io_storage driver backend. This patch is necessary to
remove the "--unresolved=el3_panic" linker flag from Tegra's
makefiles and allow us to revert this workaround, previously
suggested by the ARM toolchain team.

The "--unresolved=el3_panic" flag actually was a big hammer that
allowed Tegra platforms to work with armlink previously but it
masks legit errors with the code as well.

imx: make sure GIC redistributor is awake before initialization

GICR_WAKER.ProcessorSleep can only be set to zero when:
— GICR_WAKER.Sleep bit[0] == 0.
— GICR_WAKER.Quiescent bit[31] == 0.

On some platforms, when system reboot with GIC in sleep
mode but with power ON, such as on NXP's i.MX8QM, Linux
kernel enters suspend but could be requested to reboot,
and GIC is in sleep mode and it is inside a power domain
which is ON in this scenario, when CPU reset, the GIC
driver trys to set CORE's redistributor interface to awake,
with GICR_WAKER.Sleep bit[0] and GICR_WAKER.Quiescent bit[31]
both set, the ProcessorSleep bit[1] will never be clear
and cause system hang.

This patch makes sure GICR_WAKER.Sleep bit[0] and
GICR_WAKER.Quiescent bit[31] are both zeor before clearing
ProcessorSleep bit[1].
