[PATCH v3] staging: sm750fb: fixed a assignment typo

fixed a typo issue in get_mxclk_freq() function. the original code using PLL_CTRL_M_SHIFT for shifting to set N flag. which is not right, it should be PLL_CTRL_N_SHIFT. both PLL_CTRL_M_SHIFT and PLL_CTRL_N_SHIFT defined in drivers/staging/sm750fb/ddk750_reg.h Signed-off-by: Lynn Lei <ly
