The Innosilicon HDMI driver supports platform-specific behavior through the `inno_hdmi_plat_ops`. While it provides an `.enable` hook for platform-specific power up sequences (like enabling PHYs), it lacks a corresponding hook for power down.
This patch adds a new `.disable` op to the `inno_hdmi_plat_ops` struct and calls it at the beginning of `inno_hdmi_bridge_atomic_disable()`. This allows platform specific drivers, such as the StarFive JH7110, to implement their own power down sequence (e.g., calling phy_power_off() and clk_disable_unprepare()).
