feat(imx): add helper to take params from BL2
So far the i.MX BL31 doesn't take any parameters. This means the BL32
image base address and whether or not a BL32 image is used at all has to
be hardcoded in BL31.
This adds a helper function that allows to take params from BL2 safely.
On i.MX BL2 is usually U-Boot SPL which passes random values in arg0,
so make sure arg0 is within the internal SRAM range before accessing it
as a pointer. Also make sure arg0 is sufficiently aligned and the header
type and version is correct.
