TWRP: Enable qti input haptics vibrators support

 * these type of vibrators are present in newer devices based on
   board sm8150 & above. Like Oneplus 7 series, Redmi K20 Pro, etc.
 * to enable it add TW_SUPPORT_INPUT_1_2_HAPTICS := true in Boardconfig.mk
 * you will need to add the vendor vibrator service to init and run it in your device tree
