riscv: cpu: correctly handle the setting of CPU_FEAT_MMU bit
The conditional check to read "mmu-type" from the device tree
is not rightly handled due to which the cpu feature doesn't include
CPU_FEAT_MMU even if it's corresponding entry is present in the device
tree.
The initialization of cpu features is now taken care in cpu-uclass
driver, so no need to zero out cpu_freq in riscv_cpu driver and can be
removed.
