watchdog: RDC321X_WDT always depends on PCI

Without this dependency, platforms not supporting PCI (such as m68k) report the following build warning when building allmodconfig or allyesconfig.

drivers/watchdog/rdc321x_wdt.c: In function 'rdc321x_wdt_ioctl':
./arch/m68k/include/asm/uaccess_mm.h:61:1: warning:
'value' may be used uninitialized in this function

We could merge this into the original patch. I decided to keep it separate to avaoid having to resend that patch and to rebase my tree. Note that the SHA may change if the original patch is applied from e-mail.
