[PowerPC] Fix inclusion of dfp pseudoregs in tdep
Previously, decimal floating point pseudoregisters were always included in the target if it had a floating point unit. This patch changes this to only include them if the target description indicates that they are present, i.e. if the FPSCR register has more than 32 bits. gdb/ChangeLog: 2018-05-22 Pedro Franco de Carvalho <pedromfc@linux.vnet.ibm.com> * rs6000-tdep.c (rs6000_gdbarch_init): Assign 1 to have_dfp only if the size of fpscr is larger than 32 bits.
