ARM: i.MX8: Fix piggydata loading ...

We are running at MX8MQ_ATF_BL33_BASE_ADDR now, so we can't use
this as a temporary buffer. Add 32MiB to that address and use this
instead. Also copy the piggydata to the place where we expect it
later.

ARM: nxp-imx8mq-evk: Replace trampoline ...

When the TF-A finishes it jumps to a hardcoded address in DRAM. We used
to put a trampoline there which brings us back to our image in SRAM.
Instead of putting a trampoline into DRAM just copy the image there
which simplifies things a bit.

Note that currently imx8_esdhc_load_piggy() uses that very same address
as a temporary buffer. This is changed in the next patch. Currently the
board is broken anyway, so we don't break bisectability.

ARM: aarch64: Fix get_runtime_offset after relocation ...

get_runtime_offset shall return the offset between the address we are
running at and the address we are linked at. This value obviously
changes when we relocate the binary. cf3b09737b tried to avoid using
R_AARCH64_RELATIVE relocations, but in fact this is exactly what the
function needs to work. Consider barebox starting at 0x10000000
when we are linked at 0x0 then get_runtime_offset() should return
0x10000000 before relocate_to_current_adr(), but afterwards it should
return 0x0.

This patch brings back the previously removed "a" flag. Since gcc5
doesn't put the values of R_AARCH64_RELATIVE fixup'd relocations
into the binary but zeroes instead, we help ourselves by basing
get_runtime_offset on an address which actually is zero. With
CONFIG_RELOCATABLE=y the binary is always linked to 0x0, so _text
is initially zero.

Tested with gcc-5.4.0 (which was "fixed" by cf3b09737b) and gcc-8.2.1.

startup: Register autoboot variables earlier ...

Autoboot is controlled by autoboot_timeout and autoboot_abort_key
variables which might be altered by init scripts, so we need to
register them before those scripts are run. Otherwise they are
set back to defaultenv values upon registration.

pinctrl: i.MX iomux-v1: Make base address initialization unnecessary ...

So far we have imx_gpio_mode() to configure a pinmux entry for the older
i.MX pinmuxes. For this to work imx_iomuxv1_init() must be called
beforehand to configure the base address. Simplify this by introducing
SoC specific variants of imx_gpio_mode() which also pass the base
address. This makes initialization of the base address unnecessary and
the functions usable for PBL. Consequently also compile the code for
PBL.
