35b65dd8ef reset: Remove addr parameter from reset_cpu()
Historically, the reset_cpu() function had an `addr` parameter which was
meant to pass in an address of the reset vector location, where the CPU
should reset to.  This feature is no longer used anywhere in U-Boot as
all reset_cpu() implementations now ignore the passed value.  Generic
code has been added which always calls reset_cpu() with `0` which means
this feature can no longer be used easily anyway.

Over time, many implementations seem to have "misunderstood" the
existence of this parameter as a way to customize/parameterize the reset
(e.g.  COLD vs WARM resets).  As this is not properly supported, the
code will almost always not do what it is intended to (because all
call-sites just call reset_cpu() with 0).

To avoid confusion and to clean up the codebase from unused left-overs
of the past, remove the `addr` parameter entirely.  Code which intends
to support different kinds of resets should be rewritten as a sysreset
driver instead.

This transformation was done with the following coccinelle patch:

    expression argvalue;

    - reset_cpu(argvalue)
    + reset_cpu()

    + reset_cpu(void)

401d1c4f5d common: Drop asm/global_data.h from common header
Move this out of the common header and include it only where needed.  In
a number of cases this requires adding "struct udevice;" to avoid adding
another large header or in other cases replacing / adding missing header
files that had been pulled in, very indirectly.   Finally, we have a few
cases where we did not need to include <asm/global_data.h> at all, so
remove that include.

64272efdaf board: ge: b1x5v2: Add GE B1x5v2 and B1x5Pv2
GE B1x5v2 patient monitor series is similar to the CARESCAPE Monitor
series (GE Bx50). It consists of a carrier PCB used in combination
with a Congatec QMX6 SoM. This adds U-Boot support using device model
everywhere and SPL for memory initialization.

Proper configuration is provided as 'ge_b1x5v2_defconfig' and the
combined image u-boot-with-spi.imx can be flashed directly to 1024
byte offset to /dev/mtdblock0. Alternatively SPL and u-boot.imx can
be loaded separately via USB-OTG using e.g. imx_usb.
