i.MX: esdhc: fix imx-esdhc driver for non-OF boards ...

Commit 39f7a7ee8b68 ("i.MX: esdhc: Do not rely on CPU type for quirks")
made imx-esdhc dependent on OF and broke probing for all non-OF boards.
Since newer platforms like mx6 and vf610 are restricted to OF, the non-OF
probing only needs to distinguish mx5 vs earlier SoC.

i.MX: i2c: fix i2c-fsl for non-OF boards ...

With commit 4ed5b778a56b ("i.MX: i2c: Add Vybrid support") i2c-fsl probe
returns -EINVAL for all non-OF boards.
Since newer planforms, especially vf610 are restricted OF-only it is safe to
assume "fsl,imx21-i2c" if CONFIG_OFDEVICE is not set.

ARM: i.MX7: Add PSCI support ...

This adds the SoC specific PSCI bits for i.MX7. Based on the
corresponding U-Boot code.

ARM: Add PSCI support ...

This patch contains the barebox implementation for the ARM
"Power State Coordination Interface" (PSCI).

The interface is aimed at the generalization of code in the following
power management scenarios:
* Core idle management.
* Dynamic addition and removal of cores, and secondary core boot.
* big.LITTLE migration.
* System shutdown and reset.

In practice, all that's currently implemented is a way to enable the
secondary core one some SoCs.

With PSCI the Kernel is either started in nonsecure or in Hypervisor
mode and PSCI is used to apply power to the secondary cores.

The start mode is passed in the global.bootm.secure_state variable. This
enum can contain "secure" (Kernel is started in secure mode, means no
PSCI), "nonsecure" (Kernel is started in nonsecure mode, PSCI available)
or "hyp" (Kernel is started in hyp mode, meaning it can support
virtualization).

We currently only support putting the secure monitor code into SDRAM,
which means we always steal some amount of memory from the Kernel.
To keep things simple for now we simply keep the whole barebox binary in
memory

The PSCI support has been tested on i.MX7 only so far. The only
supported operations are CPU_ON and CPU_OFF.

The PSCI and secure monitor code is based on the corresponding U-Boot
code.

ARM: start: Fix image size calculation ...

In barebox_non_pbl_start() we do not run at the address we are linked
at, so we must read linker variables using ld_var(). Since ld_var()
current is not available on arm64 we create two zero sized arrays,
one at the begin of the image and one at the end. The difference
between both is the image size we are looking for.
