MIPS: Better abstract R2300 FPU usage in Kconfig
Introduce a CONFIG_CPU_R2300_FPU Kconfig symbol mirroring the existing CONFIG_CPU_R4K_FPU, and use it to determine whether to build r4k_fpu.S. This removes the duplicate R3000 & TX39XX cases in arch/mips/kernel/Makefile and prepares us for the possibility of disabling FP support later.
