The i.MX35 has two bits per clock gate which are decoded as follows:
      0b00 -> clock off
      0b01 -> clock is on in run mode, off in wait/doze
      0b10 -> clock is on in run/wait mode, off in doze
      0b11 -> clock is always on

The reset value for the MAX clock is 0b10.

The MAX clock is needed by the SoC, yet unused in the Kernel, so the
common clock framework will disable it during late init time. It will
only disable clocks though which it detects as being turned on. This
detection is made depending on the lower bit of the gate. If the reset
value has been altered by the bootloader to 0b11 the clock framework
will detect the clock as turned on, yet unused, hence it will turn it
off and the system locks up.

This patch turns the MAX clock on unconditionally making the Kernel
independent of the bootloader.

As we use platform_device_id for fsl-usb2-udc driver, it needs to
change clk connection-id, or the related devm_clk_get will be failed.

It moves a bunch of header files included in hardware.h and itself
from mach-imx/include/mach to mach-imx, and updates users to include
hardware.h rather than mach/hardware.h.  The files in mach-imx/devices
will need to include "../hardware.h".

It changes the driver to use platform_device_id rather than cpu_is_xxx
to determine the controller type, and updates the platform code
accordingly.

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

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.

Rename mach-imx/include/mach/common.h to mach-imx/common.h and update
all users to include common.h rather than mach/common.h.

It also removes an unneeded inclusion to common.h in

SSI block has two types of clock:

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 only need 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 SCC clock is needed in internal boot mode and so must keep enabled.

As the timer code now does a clk_get to get its clock we don't
need the struct clk argument anymore.
This also changes the alternative EPIT timer to do a clk_get.
