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.

Quoting Ye Li from NXP:

    "We have confirmed with PMIC team, 0x35 is used only on early chips
    and not used any more. 0x25 is the final address."

Fix it by merging power_pca9450a_init and power_pca9450b_init into one
function power_pca9450_init.

Move this header out of the common header.
Signed-off-by: NSimon Glass <sjg@chromium.org>

We should not use typedefs in U-Boot. They cannot be used as forward
declarations which means that header files must include the full header to
access them.

Drop the typedef and rename the struct to remove the _s suffix which is
now not useful.

This requires quite a few header-file additions.

Use the `do_reset` implementation of `arch/arm/lib/reset.c` in SPL
instead.  It is very close to what is done here, anyway, and plays
more nicely with the rest of U-Boot than adding a custom `do_reset`
implementation into board files.

`do_reset` from `arch/arm/lib/reset.c` calls `reset_cpu` with 0 as the
addr parameter while the boards are passing WDOG1_BASE_ADDR.  This is
ok because the `reset_cpu` implementation uses WDOG1_BASE_ADDR by
default if 0 is passed in.

At present panic() is in the vsprintf.h header file. That does not seem
like an obvious choice for hang(), even though it relates to panic(). So
let's put hang() in its own header.
