These two clocks connect to external pins and can be muxed to
various internal clocks.
They are typically used either for debugging or to provide
clocks to external chips (eg audio codecs).

Currently only the selectable clocks that already exist in the clock tree
have been added.

The MIPI/HSP clocks were recently turned on in the i.MX51 clock tree.
It turned out that the system does not work properly when the MIPI/HSP
clocks are enabled, but the IPU clock is disabled. This happens when
IPU support is disabled. In this case the IPU clock gets disabled when
the clock framework turns off unused clock in a late_initcall. This
is broken since:

|     ARM i.MX5: switch IPU clk support to devicetree bindings
|
|     The i.MX5 clk support has platform based clock bindings for the
|     IPU. IPU support is devicetree only, so move them over to devicetree
|     based bindings. Also, enable MIPI clocks which do not have a device
|     associated with, but still need to be enabled to do graphics on
|     i.MX51.

This patch fixes this by setting some reserved bits in the CCM as recommended
in the reference manual.

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.

As the result, mach/hardware.h inclusion gets removed from the driver.

The imx5 common clock migration causes a regression with smsc911x
driver on imx53-ard board, where a smsc lan9220 controller gets
connected on imx53 with EIM interface.  EIM needs clock emi_slow_gate
to be functional.  In the new imx5 clock driver, there is no use count
incremented for the clock by enabling it, so the framework closes the
clock at late init time and makes EIM stop working then.

Enable emi_slow_gate in clock driver initialization to fix the
regression.
