riscv: cpufeature: detect RISCV_ALTERNATIVES_EARLY_BOOT earlier 
Currently riscv_cpufeature_patch_func() does nothing at the
RISCV_ALTERNATIVES_EARLY_BOOT stage. Add a check to detect whether we
are in this stage and exit early. This will allow us to use
riscv_cpufeature_patch_func() for scanning of all ISA extensions.
