Currently, the MAC address from the second ethernet is generated from the
crypto-key (and not a customer reg) because of a wrong index to the ocotp
array.

Both imx23 and imx28 have CHIPID register at address 0x8001c310, which
can be used to identify the SoC.  This patch changes cpu_is_xxx and
__arch_decomp_setup to use this CHIPID register than machine type to
detect the chip between imx23 and imx28, so that we do not need to
change these functions whenever a new board/machine gets added.

Remove the now empty arch_reset() from all the mach/system.h includes,
and remove its callsite.  Remove arm_machine_restart() as this function
no longer does anything useful.

For samsung platforms, remove the include of mach/system-reset.h and
plat/system-reset.h from their respective mach/system.h headers as these
just define their arch_reset functions.  As a result, the s3c2410 and
plat-samsung system-reset.h files are no longer referenced, so remove
these files entirely.

We only need to set the system up for a soft-restart if we're going to
be doing a soft-restart.  Provide a new function (soft_restart()) which
does the setup and final call for this, and make platforms use it.
Eliminate the call to setup_restart() from the default handler.

This means that platforms arch_reset() function is no longer called with
the page tables prepared for a soft-restart, and caches will still be
enabled.

Noticed when setting SSP0 in clk_set_rate, _CLK_SET_RATE attempts to
reset the clock divider for the SSP0 parent clock, in this case
IO0FRAC. Bits 24-29 of HW_CLKCTRL_FRAC0 are cleared correctly, but
when the new frac value is written the value isn't shifted up to write
the correct bit-field.  This results in IO0FRAC being set to 0 and
CPUFRAC being corrupted.

This should occur when writing IO1FRAC, EMIFRAC in HW_CLKCTRL_FRAC0
and GPMIFRAC, HSADCFRAC in HW_CLKCTRL_FRAC1.

Tested on custom i.MX28 board with SSP0 SPI driver.

Some platforms (like OMAP not to name it) are doing rather complicated
hacks just to determine the base UART address to use.  Let's give their

to the macro but no one is using it yet.

Rather than marking the mach/gpio.h header files which want to use the
trivial GPIOLIB implementation, mark those which do not want to use it
instead.  This means that by default, you get the trivial implementation
and only have to do something extra if you need to.  This should
encourage the use of the trivial default implementation.

As an additional bonus, several gpio.h header files become empty.
