README: Clarify difference of CONFIG_WATCHDOG and CONFIG_HW_WATCHDOG
Now that we have the documentation, the code should be changed to reflect
it ;)
Asd far as I can see, these are the places where HW_WATCHDOG is used
instead of WATCHDOG:
arch/blackfin/cpu/blackfin/watchdog.c
arch/m68k/cpu/mcf547x_8x/cpu.c
The relevant maintainers are on CC.
