MIPS: make kgdb depend on FPU support
kgdb fails to build when the FPU support is disabled:
arch/mips/kernel/kgdb.c: In function 'dbg_set_reg':
arch/mips/kernel/kgdb.c:147:35: error: 'struct thread_struct' has no member named 'fpu'
147 | memcpy((void *)¤t->thread.fpu.fcr31, mem,
| ^
arch/mips/kernel/kgdb.c:155:34: error: 'struct thread_struct' has no member named 'fpu'
155 | memcpy((void *)¤t->thread.fpu.fpr[fp_reg], mem,
This is only relevant for CONFIG_EXPERT=y, so disallowing it
in Kconfig is an easier workaround than fixing it properly.
