Change todr_chip_handle::cookie -> todr_chip_handle::todr_dev, and
make it a device_t. Upcoming functional changes will require the
device_t associated with a TODR device.

Change todr_chip_handle::bus_cookie -> todr_chip_handle::todr_devaux.
Nothing was using the old field, but I decided to keep it around just
in cause something needs it in the future.

And with these largely mechanical yet semantically meaningful changes,
thus spake the Oracle: "Welcome to NetBSD 11.99.2."

Remove unnecessary NULL-initialization of TODR handle fields.

Trailing whitespace.

split device_t/softc for all remaining drivers.
replace "struct device *" with "device_t".
use device_xname(), device_unit(), etc.

branches: 1.5.2; 1.5.12;
#include <sys/bus.h> instead of <machine/bus.h>.

One semicolon is enough.

Remove `volatile' qualifier from argument types of
struct timeval passed to todr_gettime(9) and todr_settime(9).
We no longer have an ancient and volatile struct timeval `time'
global since we have switched to MI timercounter(9) on all port.

XXX1: some of these RTC drivers still assume 32bit time_t
XXX2: some of these should be rewritten to use todr_[gs]ettime_ymdhms()
XXX3: todr(9) man page doesn't mention todr_[gs]ettime_ymdhms()

branches: 1.2.62;
Remove unused todr_setcal/todr_getcal and all the assorted stub
implementations.

branches: 1.1.4; 1.1.8; 1.1.12; 1.1.22;
add new EP93xx device drivers.
epgpio: GPIO Interface (support gpio(4))
epled: LED on epgpio
eppcic: PCMCIA Interface
eprtc: Realtime clock
epwdog: Watchdog timer

changes
ep93xx_intr: add dummy entries to keep vmstat happy.
epclk: I use Timer1 and generate 100Hz if set.
epe: attach epclk and epgpio first.
fetch the Ethernet address from property if set.
I use config flags and modify MDCDIV.
