pci设备更新硬件设备详细厂商信息

修改lspci显示内容，说白了就是pcie设备在系统有一个配置文件，然后去修改配置文件。
cenOS该文件为/usr/share/hwdata/pci.ids ,
Ubuntu为 /usr/share/misc/pci.ids

make install

#Makefile
SRC_DIR=$(shell pwd)install:@$(SRC_DIR)pci.update $(SRC_DIR)/pci.ids

pci.ids

#这里厂商号自己随便写的，如果雷同，请见谅 1fff
1fff  MY_COMPANY0001 first dev0002 second dev0003 third dev
