hwc/overlay/hdmi: Fix / enable some error messages.

Fix cases where some errors are really warnings/info.
Print one-time events like HDMI connect disconnect as info logs.
Print the error string and type on MSMFB_OVERLAY_PREPARE failure.

An ENODEV from driver corresponds to a pipe not available and should
be treated as a warning. This could happen if a previous UNSET is
pending due to a missed vsync. ENODEV should be treated as fatal
only if it is seen continuously representing a book-keeping
blunder.
