RISC-V Patches for the 5.0 Soft Freeze, Part 1

This patch set contains a handful of collected fixes that I'd like to target
for the 5.0 soft freeze (I know that's a long way away, I just don't know what
else to call these):

* A fix for a memory leak initializing the sifive_u board.
* Fixes to privilege mode emulation related to interrupts and fstatus.

Notably absent is the H extension implementation.  That's pretty much reviewed,
but not quite ready to go yet and I didn't want to hold back these important
fixes.  This boots 32-bit and 64-bit Linux (buildroot this time, just for fun)
and passes "make check".
