Per the datasheet, the mapping between 12 and 24 hours modes is:
      0      <->  12   PM
      1-12   <->  1-12 AM
      13-23  <->  1-11 PM

Implement state save/restore for the DS1338. This requires
the usual minor adjustment of types in the state struct to
get fixed-width ones with vmstate macros.

The 'struct tm now' field in the state structure is in fact only
ever used as a temporary (the actual RTC state is held in 'offset').
Remove it from the state structure in favour of using local variables
to avoid confusion about whether it needs to be saved on migration.

The DS1338 datasheet documents that the current time is captured into
the secondary registers when the register pointer wraps round to zero
as well as at a START condition. Implement this.

Correct several deficiencies in the handling of the register pointer:
 * it should wrap around after 0x3f, not 0xff
 * guard against the caller handing us an out of range pointer
   (on h/w this can never happen, because only a 7 bit value is
   transferred over the I2C bus)
 * there was confusion over whether nvram[] holds only the 56 bytes
   of guest-accessible NVRAM, or also the secondary registers
   which hold the value of the clock captured at the start of a
   multibyte read. Correct to consistently be the latter, by fixing
   the array size and the offset used for NVRAM writes.
 * ds1338_send was attempting to use 'data' as both the data and
   the register offset simultaneously, which meant that writes to
   any register were broken; fix to use the register pointer.

Without the break statement, case 5 sets month and year from the same
data. This does not look correct.

The missing break was reported by splint.

Replace device_init() with generalized type_init().

While at it, unify naming convention: type_init([$prefix_]register_types)
Also, type_init() is a function, so add preceding blank line where
necessary and don't put a semicolon after the closing brace.

This was done in a mostly automated fashion.  I did it in three steps and then
rebased it into a single step which avoids repeatedly touching every file in
the tree.

The first step was a sed-based addition of the parent type to the subclass
registration functions.

The second step was another sed-based removal of subclass registration functions
while also adding virtual functions from the base class into a class_init
function as appropriate.

Finally, a python script was used to convert the DeviceInfo structures and
qdev_register_subclass functions to TypeInfo structures, class_init functions,
and type_register_static calls.

We are almost fully converted to QOM after this commit.

This converts two types because smbus is implemented as a subclass of i2c.  It's
extremely difficult to convert these two independently.
