kernel: Activate KERNEL_MIPS_FP_SUPPORT for pistachio target
The pistachio target uses a MIPS CPU with FPU and OpenWrt uses a
toolchain with hard FPU support. MIPS FPU support needs the FPU
emulation code in the kernel.
Fixes: ac5671f46cb4 ("kernel: remove obsolete kernel version switches for 4.19")
