sparse reports the following address space warning.
drivers/watchdog/ixp4xx_wdt.c:122:20: sparse:
incorrect type in assignment (different address spaces)
drivers/watchdog/ixp4xx_wdt.c:122:20: sparse:
expected void [noderef] __iomem *base
drivers/watchdog/ixp4xx_wdt.c:122:20: sparse:
got void *platform_data
Add a typecast to solve the problem.
Fixes: 21a0a29d16c6 ("watchdog: ixp4xx: Rewrite driver to use core")
