clk: tegra124: Remove lock-enable bit from PLLM
According to the Tegra124 TRM documentation, PLLM_MISC2 register doesn't
have the lock-enable bit as well as any other PLLM-related register. Hence
PLLM re-locking can't be initiated by software. The incorrect bit setting
should have been harmless since that bit is undefined according to TRM.
