sfc: Use lm87 and lm90 drivers for board temperature/power monitoring
Add board monitoring to periodic work whenever link is down. For SFE4001, report when a fault has caused the PHY to turn off. For SFE4002, switch XFP PHY into low-power state in case of a fault. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
