dojo: Do enable/disable nvme separately
Enable/Disable nvme sould be done separately for specific SOC PCIE
function demand. Also, set enable nvme priority to HOOK_PRIO_FIRST
when chipset resume (see bug for more details).
BUG=b:236790585
BRANCH=cherry
TEST=make sure that nvme power on timing will not cause PCIe driver
timeout when chipset resume.
