target/ppc: Fix register update on lf[sd]u[x]/stf[sd]u[x]
These instructions should update the GPR indicated by the field RA
instead of RT. This error caused a regression on Mac OS 9 boot and some
graphical glitches in OS X.
Fixes: a39a106634a9 ("target/ppc: Move load and store floating point instructions to decodetree")
