Previously, the address of the watchdog timer registers was
retrieved by calling a global function, mv64x60_get_bridge_vbase().
That function doesn't exist in arch/powerpc. Instead, we now get
the register address from a platform data resource and ioremap
the registers within the driver.

The driver previously registered its platform device data in its own
init function--that's bogus. Move that code to platform-specific
code in arch/ppc. This is being done so that the platform code can
decide at runtime whether to initialize this driver or not.

1. Ensure that the mouse and keyboard do not ping the watchdog.
This is the default operation of the w83627, but some BIOSes change this.
2. Increase the max timeout from 63 seconds to 255 seconds
as supported by the w83627 chip
3. Comment that the watchdog supports the w83627hg version of the chip

All watchdog device drivers are VFSs (Virtual File Systems).
We thus return a nonseekable_open(inode, file) when we open the VFS.

* Remove the redundant check for pwrite(), given that the open() routine
already invokes nonseekable_open().
* The WDIOF_CARDRESET flag can only be used when you can read this status
via the WDIOC_GETSTATUS ioctl call.
* Add the mandatory WDIOC_GETBOOTSTATUS ioctl call.

* Add MODULE_ALIAS_MISCDEV(WATCHDOG_MINOR);
* Add mandatory WDIOC_GETSTATUS and WDIOC_GETBOOTSTATUS ioctl's.
* If unknown ioctl is used we should return -ENOTTY.
* All watchdog device drivers are VFSs (Virtual File Systems).
We thus return a nonseekable_open(inode, file) when we open the VFS.
* Make sure that /dev/watchdog can be opened by 1 parent
* Add spin-locking to prevent that forked children can disturb
each other's operations.

In the other archs, there is more factoring of smp call code, and more care
in the use of get_cpu(). That can be a follow-up MIPS patch.
