mb/asrock/b75m-itx: Remove cpu_fan_tach_src from CMOS layout

This board inherited cmos.default and cmos.layout from asrock/h77pro4-m,
which has two CPU fan headers and a CMOS option to select which one will
provide the tachometer source.

However, the code for this was never implemented. Moreover, this board
only has one CPU fan header, rendering the option useless. This change
removes the option from cmos.layout and cmos.default.
