meta-gsj: quanta-nvme-powerctrl: Update package process

Update quanata-nvme-powerctrl process and
delete two duplication function and variable

init_once.sh:
1. Dump input pin information because of confirming HW signal.
2. HW POWER_U2 default is output high. If detect SSD is plugged, don't
   need to initialize POWER_U2 again.
3. Add RST_BMC_U2 steps, check PWRGD_U2 is fine, wait 100ms then st
   RST_BMC_U2 high.

nvme_powermanager.sh:
1. Add RST_BMC_U2 steps, check PWRGD_U2 is fine, wait 100ms then set
   RST_BMC_U2 high.
2. Independent package for power control delete nvme_main DBus property
   trigger and tranfer led trigger to nvem_main package.
