block: BFQ: update to fixed newer version
fs: fsync: Dynamic fsync toggles afsync

- When user wants to use Dyn fsync, afsync will disable and vice versa. So uthe Dyn fsync toggle can be used to switch to your preferred option
defconfig: disable DPLL_CASCADING again - it breaks HDMI output for now
hdmi_toggle: the toggle switch should not be reversed

so fix the overall code logic
defconfig: disable Fsync Control - it's obsolete now
