[MTK]马达驱动配置

在device下添加vibr服务

mediateksample/aiot8391p2_64_bsp/ProjectConfig.mk
+CUSTOM_KERNEL_VIBRATOR = vibrator

mediateksample/aiot8391p2_64_bsp/ko_order_table.csv
regulator-vibrator.ko,/../kernel_device_modules-6.1/drivers/leds/regulator-vibrator.ko,ramdisk,Y,Y,user/userdebug/eng

vendor下修改hal层

查看log是否加载了驱动，测试是否有马达震动功能，如果加载驱动没有震动功能请用adb进行测试打开。

cd sys/class/leds/vibrator/
aiot8391p2_64_bsp:/sys/class/leds/vibrator # ls
activate  brightness  device  duration  max_brightness  power  state  subsystem  trigger  uevent
aiot8391p2_64_bsp:/sys/class/leds/vibrator # echo 255 > brightness
aiot8391p2_64_bsp:/sys/class/leds/vibrator # echo 0 > brightness

如果adb测试有马达功能，那就是hal上层问题
