staging: comedi: addi_apci_3120: don't use timer 2 to count scans
Timer 2 can be used to count the number of scans when the cmd->stop_src
is TRIG_COUNT. Unfortunately that timer can also be used by userspace and
this breaks the async command. Timer 2 also only works for counting the
number of scans when DMA is not used.
The number of scans is counted by the core using the private data membmer
'scans_done'. Use that to detect the End-Of-Scan for both DMA and none
DMA modes.

staging: comedi: addi_apci_3120: introduce apci3120_ns_to_timer()
The timer divisor calculations in this driver are over complicated.
There are three timers on the board. They all use the same base clock
with a fixed prescaler for each timer. The base clock used depends on
the board version and type:
APCI-3120 Rev A boards OSC = 14.29MHz base clock (~70ns)
APCI-3120 Rev B boards OSC = 20MHz base clock (50ns)
APCI-3001 boards OSC = 20MHz base clock (50ns)
The prescalers for each timer are:
Timer 0 CLK = OSC/10
Timer 1 CLK = OSC/1000
Timer 2 CLK = OSC/1000
Add a new member to the private data, 'osc_base', to hold the base clock
time. Set this member during the board attach.
Introduce a helper function to calculate the divisor needed to generate
a nanosecond time with a given timer.
Use the new helper function in the driver to clarify the code.

The board_t has a tty_struct(serial_driver and print_driver)
that has a major number. When major number is compared in
dgap_tty_open(), just use brd->serial_driver{print_driver}->major.
