The esdctl devices are currently not in the devicetrees. this means
they are not registered when booting from the devicetree. Move the
device registration from soc_devices_init to soc_init which is called
even with devicetree support so that we get esdctl devices.

clock_notifier_call_chain() can't be called before init time. Protecting
it with IS_ENABLED(__PBL__) is not enough. This patch splits out a new
imx53_init_lowlevel_early which can be called before init time and does
not have the call to clock_notifier_call_chain() in it.

The value for i.MX53 216MHz is actually 432MHz. Use the same value
as for i.MX51 which really corresponds to 216MHz. These are the same
PLL216 values as U-Boot uses.

The pll setup function is exported, so it makes sense to export
the convenience wrappers for specific frequencies aswell.

The KARO Tx53 board in the revision 8030 has an instable SDRAM
setup. It works as long as the MMU is disabled, but the board
crashes at arbitrary places once the MMU gets enabled. So we
need the PLL setup early. Enable it for pbl.

Rather than doing this in the SoC specific code just print
it in imx_set_silicon_revision. This saves some lines of code
and also results in i.MX27 now also having the silicon revision
printed during startup.

All i.MX SoCs now use the same imx_silicon_revision() function to get
the revision. Add a separate header file for it and a common function
used on all SoCs.

The FSF address has changed in the past. Instead of updating it
each time the address changes, just drop it completely treewide.

This fix a clock inaccuracy in get_time_ns (used by sleep, time, etc).
At i.MX53 power-on GPT clock is typically 55500000 Hz, and it will be used
to calc the clock multiplier. After call imx53_init_lowlevel() GPT clock
will changed (e.g. to 66666666 Hz), but multiplier not. To fix this behavior call
clock_notifier_call_chain() after changing clock in imx53_init_lowlevel().

Some variants of the i.MX53 do not allow to run at 1GHz, so
pass a cpu frequency parameter to the lowlevel init function.

- move code which can be shared between i.MX53 and i.MX51
to a common file
- rename mx53_init_lowlevel to imx53_init_lowlevel

This adds lowlevel (AIPS, PLL, L2) initialization for i.MX53 boards.
This is a direct transcription of Freescales U-Boot assembler code
with the exception that we initialize PLL1 with 1000MHz and assume
that all necessary voltages are already adjusted when we arrive here.
It must be explicitely called from the boards so a board is free to
do it's own initialization. However, boards should use this code
and make it more configurable if necessary.

To allow for some generic io accessors introduce io.h and use
this instead of asm/io.h throughout the tree.
