If we fail to attach the first time (especially: EPROBE_DEFER), we fail to clean up 'usage_mode', and thus will fail to attach on any subsequent attempts, with "dsi controller already in use".
Re-set to DW_DSI_USAGE_IDLE on attach failure.
This is especially common to hit when enabling asynchronous probe on a duel-DSI system (such as RK3399 Gru/Scarlet), such that we're more likely to fail dw_mipi_dsi_rockchip_find_second() the first time.

Applied, thanks!
