This patch adds definitions for some DM365 IRQs that are used by
the codecs. Codecs will also use the IRQs.
Entries are being added to enable/disable IRQ's.
There is no use as such for these entires in the kernel itself.
Instead these will be used by the "linuxutils" package of the DVSDK.

DA850/OMAP-L138 has 144 pins configurable as GPIO, but
currently this has been configured as 128. This patch
corrects it.

Also, this patch adds the base address for GPIO pins
greater than 128.

The DA850/OMAP-L138 is a new SoC from TI in the same family as
DA830/OMAP-L137.

Major changes include better support for power management,
support for SATA devices and McBSP (same IP as DM644x).

DA850/OMAP-L138 documents are available at

The da830/omap l137 is a new SoC from TI that is similar
to the davinci line.  Since its so similar to davinci,
put the support for the da830 in the same directory as
the davinci code.

There are differences, however.  Some of those differences
prevent support for davinci and da830 platforms to work
in the same kernel binary.  Those differences are:

1) Different physical address for RAM.  This is relevant
   to Makefile.boot addresses and PHYS_OFFSET.  The
   Makefile.boot issue isn't truly a kernel issue but
   it means u-boot won't work with a uImage including
   both architectures.  The PHYS_OFFSET issue is
   addressed by the "Allow for runtime-determined
   PHYS_OFFSET" patch by Lennert Buytenhek but it
   hasn't been accepted yet.

2) Different uart addresses.  This is only an issue
   for the 'addruart' assembly macro when CONFIG_DEBUG_LL
   is enabled.  Since the code in that macro is called
   so early (e.g., by _error_p in kernel/head.S when
   the processor lookup fails), we can't determine what
   platform the kernel is running on at runtime to use
   the correct uart address.

These areas have compile errors intentionally inserted
to indicate to the builder they're doing something wrong.

A new config variable, CONFIG_ARCH_DAVINCI_DMx, is added
to distinguish between a true davinci architecture and
the da830 architecture.

Note that the da830 currently has an issue with writeback
data cache so CONFIG_CPU_DCACHE_WRITETHROUGH should be
enabled when building a da830 kernel.

Use the SoC infrastructure to hold the interrupt controller
information (i.e., base address, default priorities,
interrupt controller type, and the number of IRQs).

The interrupt controller base, although initially put
in the soc_info structure's intc_base field, is eventually
put in the global 'davinci_intc_base' so the low-level
interrupt code can access it without a dereference.

These changes enable the SoC default irq priorities to be
put in the SoC-specific files, and the interrupt controller
to be at any base address.
