This patch fixes a programming error by limiting WDT_TIMEOUT_MAX to 255.
That is done to avoid invalid settings. Putting a value bigger than 255
results in non working watchdog and reset is not performed. We are trying
to fit a 10bit value to an 8bit area! To support 1023 seconds MMIO addr+5
bit1:0 must be used to store the last(higher) two bits of count number.
Strangely no error was logged at the system when using values bigger than
255, the driver just ignores the time count.
Also it adds support for VT8235 and VT8237 series southbridges. Tested with
VT8235M, VT8237 and VT8237S boards.
Sending patch to stable too since it seems like an overflow error if big
timeout values are chosen and because those chipsets were very popular in
x86 boards supporting processors from all vendors (AMD, intel and VIA).
