The am35x family of SoCs has a Davinci EMAC ethernet
controller on-chip. Unfortunately, the EMAC is unable
to wake the PRCM when there is network activity which
leads to a hung or extremely slow system when the MPU
has executed a 'wfi' instruction (because of pm_idle
or CPUidle). To prevent this, add hooks to the EMAC
pm_runtime suspend/resume calls so that hlt is disabled
whenever the EMAC is in use.
