[SeaBIOS] [PATCH] boot: Show boot splash until all threads are complete

[Paul Menzel]

[Please find the unmangled patch attached. I have no idea how to turn 
off line wrapping in Mozilla Thunderbird.]

Currently, even with `etc/threads` set to 2 in CBFS, the boot splash is
only shown for a short period, while SeaBIOS detects the hard disk on
the ASRock E350M1, which takes 10 seconds with this particular hard
drive model.

So move the call to wait for the threads to finish further up, so it is
before the instruction to disable the boot splash.

On the ASRock E350M1 the boot splash is shown the whole time now. Note,
sometimes the GRUB menu from the MBR is not shown, and boot splash can
still  be seen. The screen only changes, once the Linux kernel boots.
This seems to be a GRUB issue though [1].
