84a3a53cf6 omap: Don't use hw_error() in device init() methods
Device init() methods aren't supposed to call hw_error(), they should
report the error and fail cleanly.  Do that.

The errors are all device misconfiguration.  All callers use
qdev_init_nofail(), so this patch merely converts hw_error() crashes
into &error_abort crashes.  Improvement, because now it crashes closer
to where the misconfiguration bug would be, and a few more bad
examples of hw_error() use are gone.

bd2a88840e Convert ffs() != 0 callers to ctz32()
There are a number of ffs(3) callers that do roughly:

  bit = ffs(val);
  if (bit) {
      do_something(bit - 1);
  }

This pattern can be converted to ctz32() like this:

  zeroes = ctz32(val);
  if (zeroes != 32) {
      do_something(zeroes);
  }

1b111dc121 hw: cannot_instantiate_with_device_add_yet due to pointer props
Pointer properties can be set only by code, not by device_add.  A
device with a pointer property can work with device_add only when the
property may remain null.

This is the case for property "interrupt_vector" of device
"etraxfs,pic".  Add a comment there.

Set cannot_instantiate_with_device_add_yet for the other devices with
pointer properties, with a comment explaining why.

Juha Riihimäki and Peter Maydell deserve my thanks for making "pointer
property must not remain null" blatantly obvious in the OMAP devices.

Only device "smbus-eeprom" is actually changed.  The others are all
sysbus devices, which get cannot_instantiate_with_device_add_yet set
in their abstract base's class init function.  Setting it again in
their class init function is technically redundant, but serves as
insurance for when sysbus devices become available with device_add,
and as documentation.
