[Core] usb_device_state
: consolidate usb state handling across implementations (#24258)
* usb_device_state: add idle_rate, led and protocol Previously all usb drivers and platform implementations (expect for our oddball atsam) tracked the same two global variables: - keyboard_protocol: to indicate if we are in report or boot protocol - keyboard_idle: for the idle_rate of the keyboard endpoint And a local variable that was exposed trough some indirection: - keyboard_led_state: for the currently set indicator leds (caps lock etc.) These have all been moved into the usb_device_state struct wich is accessible by getters and setters. This reduces code duplication and centralizes the state management across platforms and drivers. Signed-off-by: Stefan Kerkmann <karlk90@pm.me> * usb_device_state: reset protocol on reset The usb hid specification section 7.2.6 states: When initialized, all devices default to report protocol. However the host should not make any assumptions about the device’s state and should set the desired protocol whenever initializing a device. Thus on reset we should always do exactly that.
