Katsuhiro Suzuki 59903e2934 kernel: arch: introduce k_float_enable() ... This patch introduce new API to enable FPU of thread. This is pair of existed k_float_disable() API. And also add empty arch_float_enable() into each architectures that have arch_float_disable(). The arc and riscv already implemented arch_float_enable() so I do not touch these implementations. Motivation: Current Zephyr implementation does not allow to use FPU on main and other system threads like as work queue. Users need to create an other thread with K_FP_REGS for floating point programs. Users can use FPU more easily if they can enable FPU on running threads.
