HID: use hid_hw_request() instead of direct call to usbhid

This allows the hid drivers to be independent from the transport layer.

The patch was constructed by replacing all occurences of
usbhid_submit_report() by its hid_hw_request() counterpart.
Then, drivers not requiring USB_HID anymore have their USB_HID
dependency cleaned in the Kconfig file.

Finally, few drivers still depends on USB_HID. Many of them
are requiring the io wait callback. They are found in the next patch.

HID: picolcd: fix build error if !CONFIG_DEBUG_FS

Current code missed the definition for picolcd_debug_out_report, but add
definition for picolcd_debug_raw_event twice.

This patch fixes below build error:

HID: picoLCD: rework hid-fbdev interaction

Split out all FB related data out of struct picolcd_data into a struct
picolcd_fb_data that is allocated with fb_info. This way fb_info may
cleanly outlive struct picolcd_data for as long as needed for its last
user to drop his reference.

Access to struct picolcd_data is now protected with struct
picolcd_fb_data's lock and tile update reports are only generated
while picolcd_fbdata->picolcd is not NULL and is not marked as failed
(which indicates unplug in progress).
