Define an enum for gpt timer device type in include/soc/imx/timer.h to
tell the gpt block differences among SoCs.  Update non-DT users (clock
drivers) to pass the device type.

As we now have include/soc/imx/timer.h, the declaration of
mxc_timer_init() is moved into there as the best fit.

Instead of calling cpu_is_xxx() in clk-pllv1 driver, let's add clk-pllv1

Doing so will help get clk-pllv1 driver ready for being moved out of

imx ssi block has two types of clocks:

- ipg: bus clock, the clock needed for accessing registers.
- per: peripheral clock, the clock needed for generating the bit rate.

Currently ssi driver only supports slave mode and thus need only to handle
the ipg clock, because the peripheral clock comes from the master codec.

Only register the ipg clock and do not register the peripheral clock for ssi

The i.MX27 clock tree can either be driven from a 26MHz oscillator
or from a 32768Hz oscillator. The latter was not properly implemented,
the mux between these two pathes was missing. Add this mux and while
at it rename the 'prem' (premultiplier) clk to 'fpm' (Frequency

This is some amount of work left/forgot from device tree conversion.
Instead of checking cpu_is_xxx to determine the controller type, the
driver should use platform_device_id, which should match the device
tree compatible string.

The patch changes the driver to use platform_device_id rather than
cpu_is_xxx to determine the controller type/version.  It also updates
the platform code and device tree source accordingly.
