Commit 59d3ae9a5bf6 ("ARM: remove Intel iop33x and iop13xx support")
removes the config ARCH_IOP13XX in ./arch/arm/Kconfig.
Hence, since then, the corresponding iop watchdog timer driver is dead
code. Remove this dead driver.

I would add a reference to ec2e32ca661e ("watchdog: iop_wdt only builds for
mach-iop13xx") in the changelog, before that it could be selected but
did not build.
