Since GDB 13.1(GDB commit ea3352172), GDB LoongArch changed to use
fcc0-7 instead of fcc register. This commit partially reverts commit
2f149c759 (`target/loongarch: Update gdb_set_fpu() and gdb_get_fpu()`)
to match the behavior of GDB.

Note that it is a breaking change for GDB 13.0 or earlier, but it is
also required for GDB 13.1 or later to work.

the API with target specific stuff.

Note we have to include cpu.h in semihosting as it was relying on a
