Fix for 8Bitdo_M30_24G.cfg to work as genesis controller

[ArkhangelAzrael]

Currently the dinput/8Bitdo_M30_24G.cfg is setup to work as a x-input Xbox-like controller. I believe that it would be better to have it setup as a genesis 6B controller, in the same form as the dinput/8Bitdo_M30_BT.cfg was changed here: PitiBatou#2.

Here is a working config:

# 8BitDo M30 2.4g controller

input_device_display_name = "8BitDo M30 2.4g"
input_driver = "dinput"
input_device = "6B controller"
input_vendor_id = "3235"
input_product_id = "36"

# Buttons:
input_b_btn = "1"
input_a_btn = "5"
input_x_btn = "0"
input_y_btn = "2"
input_up_axis = "-1"
input_down_axis = "+1"
input_left_axis = "-0"
input_right_axis = "+0"
input_l_btn = "3"
input_r_btn = "4"
input_select_btn = "8"
input_start_btn = "9"

input_b_btn_label = "B"
input_a_btn_label = "C"
input_x_btn_label = "Y"
input_y_btn_label = "A"
input_up_axis_label = "D-Pad Up"
input_down_axis_label = "D-Pad Down"
input_left_axis_label = "D-Pad Left"
input_right_axis_label = "D-Pad Right"
input_l_btn_label = "X"
input_r_btn_label = "Z"
input_select_btn_label = "Mode"
input_start_btn_label = "Start"

# D-Pad:
input_up_axis = "-1"
input_down_axis = "+1"
input_left_axis = "-0"
input_right_axis = "+0"

input_up_btn_label = "D-Pad Up"
input_down_btn_label = "D-Pad Down"
input_left_btn_label = "D-Pad Left"
input_right_btn_label = "D-Pad Right"

An observation I have noticed here is even if you plug this configuration in the controller still will only be recognized as 8Bitdo_M30_24G ONLY if its wireless. If you plug the controller in via USB its gets recognized as Generic 360 Controller.

Also I don't see any issue with the default wireless config in Retroarch which this file currently runs on, its only when its Wired does Retroarch misconfigure and its not due to this file.
