Convert the struct i2c_msg initialization to C99 format. This makes
maintaining and editing the code simpler. Also helps once other fields
like transferred are added in future.

When detecting power failure, the probe function would reset the clock
time to defined state.
However, the clock's _date_ might still be bogus and a subsequent probe
fails when sanity-checking these values.
Change the power-failure fixup code to do a full setting of rtc_time,
including a valid date.

The possible CCR_Y2K register values are 19 or 20 and struct rtc_time's
tm_year is in years since 1900.
The function translating rtc_time to register values assumes tm_year to be
years since first christmas, though, and we end up storing 0 or 1 in the
CCR_Y2K register, which the hardware does not refuse to do.
A subsequent probing of the clock fails due to the invalid value range in
the register, though.
[ And if it didn't, reading the clock would yield a bogus year because
the function translating registers to tm_year is assuming a register
value of 19 or 20. ]
This fixes the conversion from years since 1900 in tm_year to the
corresponding CCR_Y2K value of 19 or 20.

I have discovered that the current version of rtc-x1205.c does not work
correctly when asked to set the alarm time by the RTC_WKALM_SET ioctl()
call. This happens because the alarm registers do not behave like the
current-time registers. They are non-volatile. Two things go wrong:
- the X1205 requires a 10 msec delay after any attempt to write to the
non-volatile registers. The x1205_set_datetime() routine does the write
as 8 single-byte writes without any delay. Only the first write
succeeds. The second is NAKed because the chip is busy.
- the X1205 resets the RWEL bit after any write to the non-volatile
registers. This would lock out any further writes after the first even
with a 10msec delay.
I fix this by doing a single 8-byte write and then waiting 10msec for the
chip to be ready. A side effect of this change is that it will speed up
x1205_rtc_set_time() which uses the same code.
I have also implemented the 'enable' bit in the rtc_wkalm structure, which
the existing driver does not attempt to do. I have modified both
x1205_rtc_set_alarm() to set the AL0E bit, and x1205_rtc_read_alarm() to
return it.
I have tested this patch on a LinkSys NSLU2 under OpenWRT, but on no other
hardware. On the NSLU2 the X1205 correctly asserts its IRQ pin when the
alarm time matches the current time.

Based on earlier work by Jon Smirl and Jochen Friedrich.
Update most new-style i2c drivers to use standard module aliasing
instead of the old driver_name/type driver matching scheme. I've
left the video drivers apart (except for SoC camera drivers) as
they're a bit more diffcult to deal with, they'll have their own
patch later.

Based on earlier work by Jon Smirl and Jochen Friedrich.
This patch allows new-style i2c chip drivers to have alias names using
the official kernel aliasing system and MODULE_DEVICE_TABLE(). At this
point, the old i2c driver binding scheme (driver_name/type) is still
supported.

Update more I2C drivers that live outside drivers/i2c to understand that using
adapter->dev is not The Way. When actually referring to the adapter hardware,
adapter->class_dev.dev is the answer. When referring to a device connected to
it, client->dev.dev is the answer.

A port of the existing x1205 driver under the new RTC subsystem.
It is actually under test within the NSLU2 project
(http://www.nslu2-linux.org) and it is working quite well.
It is the first driver under this new subsystem and should be used as a guide
to port other drivers.
