Make the IOMMU platform data target-independent in
preparation for adding MSM8960 IOMMU support. The IOMMU
configuration on MSM8x60 and MSM8960 is identical and the
same platform data can be used for both.

The QGIC registers are mapped to the same virtual addresses across
targets, only the physical address changes. Move the BASE address out
of target-specific files, and add a SOC name to the base addresses.

Allow the timer register to be determined dynamically instead of at
compile time. Use common virtual addresses for the registers across
all MSM chips, and select the register mappings based on the detected
CPU.

The msm provides timer hardware that is private to each core. Each
timer has separate counter and match registers, so we create separate
clock_event_devices for each core. For the global clocksource, use
cpu 0's counter.

Add the 'gpiomux' api, which addresses the following shortcomings
of existing tlmm api:
- gpio power-collapse, which is managed by a peripheral processor on
other targets, must be managed by the application processor on the 8x60.
- The enable/disable flag of the legacy gpio_tlmm_config api
is not applicable on the 8x60, and causes confusion.
- The gpio 'direction' bits are meaningless for all func_sel
configurations except for generic-gpio mode (func_sel 0), in which
case the gpio_direction_* functions should be used. Having these
bits in the tlmm api leads to confusion and misuse of the gpiolib
api, and they have been removed in gpiomux.
- The functional api of the legacy system ran contrary to the typical
use-case, which is a single massive configuration at boot. Rather
than forcing hundreds of 'config' function calls, the new api
allows data to be configured with a single table.
gpiomux_get and gpiomux_put are meant to be called automatically
when gpio_request and gpio_free are called, giving automatic
gpiomux/tlmm control to those drivers/lines with simple
power profiles - in the simplest cases, an entry in the gpiomux table
and the correct usage of gpiolib is all that is required to get proper
gpio power control.
