Add the necessary DT nodes to probe the clock controllers on MSM
devices as well as hook up the uart nodes to the clock
controllers. This should allow us to boot to a serial console on
all DT enabled MSM platforms.

The summary interrupt is #16 in the SPI space. Unfortunately,
when this device was translated from board files to DT we forgot
to subtract 16 from the interrupt number to translate it into a
SPI interrupt. Also, the register space is larger than 4k, increase
it appropriately so that the gpio driver doesn't try to access
registers outside of its mapping.

Let's follow the ratified DT binding and use uartdm instead of
hsuart. This does break backwards compatibility but this
shouldn't be a problem because the uart driver isn't probing on
these devices without adding clock support (which isn't merged so
far).

This cleans up the gpio-msm-v2 driver of all the global define usage.
The number of gpios are now defined in the device tree. This enables
adding irqdomain support as well.

Some bad copy/paste got in as well as too many zeroes. Fix
everything up so that the registers after the @ sign are
consistent with the first reg property.

The SSBI bus is exclusive to the Qualcomm MSM targets, and all SoCs
using it will be using device tree.  Convert this driver to indentify
with device tree.

This makes the bus probing a good bit simpler, since the attaching of
child nodes can be represented directly in the devicetree, rather than
having to be inferred by name.

The msm timer binding I wrote is bad. First off, the clock
frequency in the binding for the dgt is wrong. Software divides
down the input rate by 4 to achieve the rate listed in the
binding. We also treat each individual timer as a separate
hardware component, when in reality there is one timer block
(that may be duplicated per cpu) with multiple timers within it.
Depending on the version of the hardware there can be one or two
general purpose timers, status and divider control registers, and
an entirely different register layout.

In the next patch we'll need to know about the different register
layouts so that we can properly check the status register after
clearing the count. The current binding makes this complicated
because the general purpose timer's reg property doesn't indicate
where that status register is, and in fact it is beyond the size
of the reg property.

Clean all this up by just having one node for the timer hardware,
and describe all the interrupts and clock frequencies supported
while having one reg property that covers the entire timer
register region. We'll use the compatible field in the future to
determine different register layouts and if we should read the
status registers, etc.
