net: dsa: bcm_sf2: Do not rely on kexec_in_progress
After discussing with Eric, it turns out that, while using
kexec_in_progress is a nice optimization, which prevents us from always
powering on the integrated PHY, let's just turn it on in the shutdown
path.
This removes a dependency on kexec_in_progress which, according to Eric
should not be used by modules
