Add generic DMA device tree binding for mxs-dma.  The changes include:

 * Add channel interrupts into DMA controller nodes
 * Add properties '#dma-cells' and 'dma-channels' for DMA controller nodes
 * And properties 'dmas' and 'dma-names' for DMA client nodes
 * Update mxs-dma device tree binding doc

The issue fixed by this patch manifests only then using X11
with mxsfb driver. The X11 will display either shifted image
or otherwise distorted image on the LCD.

The problem is that the X11 tries to reconfigure the framebuffer
and along the way calls fb_ops.fb_set_par() with X11's desired
configuration values. The field of particular interest is
fb_info->var.sync which contains non-standard values if
configured by kernel. These are either FB_SYNC_DATA_ENABLE_HIGH_ACT,
FB_SYNC_DOTCLK_FAILING_ACT or both, depending on the platform
configuration. Both of these values are defined in the
include/linux/mxsfb.h file.

The driver interprets these values and configures the LCD controller
accordingly. Yet X11 only has access to the standard values for this
field defined in include/uapi/linux/fb.h and thus, unlike kernel,
omits these special values. This results in distorted image on the
LCD.

This patch moves these non-standard values into new field of the
mxsfb_platform_data structure so the driver can in turn check this
field instead of the video mode field for these specific portions.

Moreover, this patch prefixes these values with MXSFB_SYNC_ prefix
instead of FB_SYNC_ prefix to prevent confusion of subsequent users.

887cbce0 "arch Kconfig: centralise CONFIG_ARCH_NO_VIRT_TO_BUS"
and  4febd95a "Select VIRT_TO_BUS directly where needed" from
Stephen Rothwell changed globally how CONFIG_VIRT_TO_BUS is
selected, while my own a5d533ee "ARM: disable virt_to_bus/
virt_to_bus almost everywhere" was merged at the same time and
changed which platforms select it on ARM.

The result of this conflict was that we again see CONFIG_VIRT_TO_BUS
on all ARM systems. This patch fixes up the problem and removes
CONFIG_ARCH_NO_VIRT_TO_BUS again on ARM.

With recent arm broadcast time clean-up from Mark Rutland, the dummy
broadcast device is always registered with timer subsystem. And since
the rating of the dummy clock event is very high, it may be preferred
over a real clock event.

This is a change in behavior from past and not an intended one. So
reduce the rating of the dummy clock-event so that real clock-event
device is selected when available.

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.
