    soc: imx: imx8mp-blk-ctrl: register HSIO PLL clock as bus_power_dev child
    
    [ Upstream commit 53cab4d871690c49fac87c657cbf459e39c5b93b ]
    
    The blk-ctrl device is deliberately placed outside of the GPC power
    domain as it needs to control the power sequencing of the blk-ctrl
    domains together with the GPC domains.
    
    Clock runtime PM works by operating on the clock parent device, which
    doesn't translate into the neccessary GPC power domain action if the
    clk parent is not part of the GPC power domain. Use the bus_power_device
    as the parent for the clock to trigger the proper GPC domain actions on
    clock runtime power management.
