The OMAP Mailbox driver framework is moved out of arch/arm folder
into drivers/mailbox folder, to re-enable building it and also serve
as a baseline for adapting to the new mailbox driver framework. The
changes mainly contain:
- a minor bug fix and cleanup of mach-specific mailbox code
- remove any header dependencies from plat-omap for multi-platform
support
- represent mailbox device data through platform data/hwmod attrs
- move the omap mailbox code out of plat-omap/mach-omapX to
drivers/mailbox folder

This patch enables usage of DT property 'gpmc,num-cs' as already documented in
Documentation/devicetree/bindings/bus/ti-gpmc.txt
Though GPMC hardware supports upto 8 chip-selects, but all chip-selects may
not be available for use because:
- chip-select pin may not be bonded out at SoC device boundary.
- chip-select pin-mux may conflict with other pins usage.
- board level constrains.
gpmc,num-cs allows user to configure maximum number of GPMC chip-selects
available for use on any given platform. This ensures:
- GPMC child nodes having chip-selects within allowed range are only probed.
- And un-used GPMC chip-selects remain blocked.(may be for security reasons).

dw_apb_timer_init used to search the devicetree for matching timer
devices, making calls to it from board files necessary.
Change the dw_apb_timer_init to work with CLOCKSOURCE_OF_DECLARE.
With this change the function gets called once for each timer node
and tracks these number of calls to attach clockevent and clocksource
devices to the nodes.
Also remove the calls to dw_apb_timer_init from all previous users, as
clocksource_of_init is the default for init_time now.

The mailbox hardware (in OMAP) uses a queued mailbox interrupt
mechanism that provides a communication channel between processors
through a set of registers and their associated interrupt signals
by sending and receiving messages.
The OMAP mailbox framework/driver code is moved to be under
drivers/mailbox, in preparation for adapting to a common mailbox
driver framework. This allows the build for OMAP mailbox to be
enabled (it was disabled during the multi-platform support).
As part of the migration from plat and mach code:
- Kconfig symbols have been renamed to build OMAP1 or OMAP2+ drivers.
- mailbox.h under plat-omap/plat/include has been split into a public
and private header files. The public header has only the API related
functions and types.
- The module name mailbox.ko from plat-omap is changed to
omap-mailbox.ko
- The module name mailbox_mach.ko from mach-omapX is changed as
mailbox_omap1.ko for OMAP1
mailbox_omap2.ko for OMAP2+

The different generations of OMAP2+ SoCs have almost the same
mailbox IP, but the IP has configurable parameters for number
of users (interrupts it can generate out towards processors)
and number of fifos (the base unidirectional h/w communication
channel). This data cannot be read from any registers, and so
has been added to the platform data.
This data together with the interrupt-type configuration can be
used in properly figuring out the number of registers to save
and restore in the OMAP mailbox driver code.

The OMAP mailbox platform driver code has been cleaned up to
remove the dependencies with soc.h in preparation for moving
the mailbox code to drivers folder.
The code relied on cpu_is_xxx/soc_is_xxx macros previously to
pick the the right set of mailbox devices and register with the
mailbox driver. This data is now represented in a concise format
and moved to the respective omap_hwmod data files and published
to the driver through the platform data.
