lwmon5: watchdog POST fix
Use the GPT0_MASKx registers as the temporary storage for watch-dog timer POST test instead of GPT0_COMPx. The latter (GPT0_COMP1..GPT0_COMP5) are used for the log-buffer header. Signed-off-by: Sergei Poselenov <sposelenov@emcraft.com> Signed-off-by: Yuri Tikhonov <yur@emcraft.com>
