gdbstub/sh4: fix build with USE_SOFTFLOAT_STRUCT_TYPES 

We have to use different type to access float values when
USE_SOFTFLOAT_STRUCT_TYPES is defined.

Rework SH4 version of cpu_gdb_{read,write}_register() using
a single case, and fixing the coding style. Use ldll_p() and
stfl_p() to access float values.
