The board has an 8254 timer/counter. Add support for this subdevice.
According to the manual I linked to, sections 3.2, 3.2.5.1 and 3.2.5.2
indicate that CLK_DATA (your MULTIQ3_CLK_REG) is write-only. This means
the INSN_CONFIG_8254_READ_STATUS config instruction and the insn_read
handler won't work, although INSN_CONFIG_8254_READ_STATUS could be
partially emulated (see below).
It's probably best just to leave the 8254 unsupported though, as it
doesn't appear to be useful for much!
