watchdog: lenovo_se10_wdt: add HAS_IOPORT dependency

Once the inb()/outb() helpers become conditional, the newly added driver
fails to link on targets without CONFIG_HAS_IOPORT:

In file included from arch/arm64/include/asm/io.h:299,
                 from include/linux/io.h:14,
                 from drivers/watchdog/lenovo_se10_wdt.c:8:
drivers/watchdog/lenovo_se10_wdt.c: In function 'set_bram':
include/asm-generic/io.h:596:15: error: call to '_outb' declared with attribute error: outb() requires CONFIG_HAS_IOPORT
  596 | #define _outb _outb
include/asm-generic/io.h:655:14: note: in expansion of macro '_outb'
  655 | #define outb _outb
      |              ^~~~~
drivers/watchdog/lenovo_se10_wdt.c:67:9: note: in expansion of macro 'outb'
   67 |         outb(offset, bram_base);
      |         ^~~~

Add the same dependency we added to the other such drivers.
