PATCH v3 1/1 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
