    Unless there is a xorg.conf option, don't modify mclck neither mxclck.
    
      The option set_mclck was renamed to just MCLK, and a new MXCLCK option
    was added for smi501/502 chips.
      Note that previously, on MSOC chips, the set_mclck option actually
    changed mxclck, what is now done by the MXCLK option.
      The manpage was also update to reflect the options usage.
      A new SMI501_FindMemClock() function was added, as a possible
    placeholder for choosing alternate clocks when programming MMIO 0x68.
    But it should be noted that the smi 501 databook says:
    Miscellaneous Timing
    	Read/Write MMIO_base + 0x000068
    	Power-on Default 0x00000000
    	[...]
    	5:4 Divider Output Frequency Selection for Second PLL.
    		00: 336 MHz.
    		01: 288 MHz.
    		10: 240 MHz.
    		11: 192 MHz.
    while the 502 databook says:
    	Miscellaneous Timing
    	Read/Write MMIO_base + 0x000068
    	Power-on Default 0b0000.00xx.0000.1001.0000.1001.0000.0000
    	[...]
    	5:4 Reserved These bits are reserved.
    but still tells to refer to those bits.
