Currently it is not understood how to properly control the horizontal
capture resolution on 24xxx devices.  The pvrusb2 driver is doing
everything it should (pass resolution paramter(s) to cx2341x and
cx25840 modules) but for some reason the result is corrupted video if
any resolution other than 720 is used.  This patch causes the driver
to only permit a horizontal resolution of 720 to be used on 24xxx
devices.  Even if the app requests something else, the driver will
force the resolution back to 720.  This patch still allows full
control of the resolution for 29xxx devices.
