The MXL5007T tuner will lock-up on some devices after an I2C read
transaction.  This patch works around this issue by inhibiting such
operations and emulating a 0x00 response. The workaround is only
applied to USB devices known to exhibit this flaw.

This patch will modify the af9035 driver to use the register address
fields of the I2C read command for the combined write/read transaction
case.  Without this change, the firmware issues just a I2C read
transaction without the preceding write transaction to select the
register.
