[WATCHDOG] Add support for 1533 bridge to alim1535_wdt

From: Andrey Borzenkov <arvidjaar@mail.ru>

They are apparently pretty close (even lspci combines them). The patch
adds support for 0x1533 bridge in addition to 0x1535.

Tested on Toshiba Portege 4000 with

00:07.0 ISA bridge [0601]: ALi Corporation M1533/M1535 PCI to ISA Bridge
[Aladdin IV/V/V+] [10b9:1533]
00:08.0 Bridge [0680]: ALi Corporation M7101 Power Management Controller
[PMU] [10b9:7101]

with result

[ 2090.906736] PCI: Enabling device 0000:00:08.0 (0000 -> 0001)
[ 2090.914034] ALi_M1535: initialized. timeout=3D60 sec (nowayout=3D0)
