meta-quanta: meta-gsj: Add quanta-nvme-powerctrl service

Add quanta-nvme-powerctrl which included three features:
1. When BMC bootup, initial nvme ssd powoer output.
2. monitor ssd present update ssd power output.
3. Add bucstl commands to set Present property to d-bus
   nvme manager and set fault led if needed.

+### NVME SSD Power Control Manager
+
+#### Description
+    The Package is Mantain for SSD power control and related noification handle Deamon
+
+#### Design
+     nvme_gpio.service for initinal related GPIOs ( PRESENT, PWR, PWRGD, RST_U2 ) and according PRESENT signal fix HW PWR default output signal. 
+
+     nvme_powermanager.service loop for monitor PRESENT signal and update PWR output.
+
+#### Process
+
+    * Plugging 
+        1. U2_[SSD_index]PRSNT_N will be input low
+        2. Set PWR_U2_[SSD_index]_EN to high
+        3. Check PWRGD_U2_[SSD_index] is high
+        4-1. If PWRGD_U2_[SSD_index] is high (PWR Good)
+		    - Wait 5ms
+		    - Enable PCI Clock by SMBus 9FGL0851
+		    - Wait 100ms
+            - Reset RST_BMC_U2 [low->high]
+		    - Send Assert to tell package could read SSD status.
+
+        4-2. If PWRGD_U2_[SSD_index] is low (PWR Fail)
+		    - Disable Clock by SMBus
+		    - Wait 100ms
+		    - Set RST_BMC_U2_[SSD_index]_R_N to low
+		    - Set LED_U2_FAULT to high
+
+    * Removing
+        1. U2_[SSD_index]PRSNT_N will be input high
+        2. Disable Clock by SMBus 9FGL0851
+        3. PWR_U2_[SSD_index]_EN to low
+        4. Check PWRGD_U2_[SSD_index] is low
+        5. Send Assert to tell package update SSD status.
+
+
+#### TODO
+    
+    1. After power on ssd, bmc  send command to 9FGL0851 (on SMBus8 0x68) for enable PCI clock, and send RST_BMC_U2 pin rsing event (set low, wait 500ms, set high). The Host could rescan PCI and detect SSD device.
+
+#### Test
+
+    1. PRESENT detect SSD: The Default Hardware is implement.
+    2. Initial SSD slot Power output: nvme_gpio service has test on Module. It could sucess initial gpios and setting correct power output.
+    3. Detect PRESENT and change power setting: nvme_powermanager service has tested on Module. It could success detect SSD plugged or removal change PWR output.
+    4. NVME-MI connect: Ensure SSD power is ready then it will notify quanta NVME-MI package could read SSD information. 
+    5. FAULT LED handle: When detect power output irregular by PWRGD pin, the service will trigger related FAULT LED.
