Hwmod needs database of all IPs in a system. This patch generates the hwmod
database for Display Sub System applicable for OMAP3430 and
OMAP36xx.  DSS is also considered as an IP as DISPC, RFBI and named as dss_core.
For all the IP modules in DSS, same clock is needed for enabling. Hwmod sees
DSS IPs as independent IPs, so same clock has to be repeated for .main_clk in
each IP.

This patch defines separate hwmod databases for OMAP3430ES1 and (OMAP3430ES2 and
OMAP36xx) as OMAP3430ES1 does not have IDLEST bit to poll on for dss IP, and also
the firewall regions are different between 3430es1 and later.

OMAP3 hwmod data structures are populated for USBOTG with base address,
L3 and L4 interface clocks, IRQs and sysconfig register details.
This is applicable for OMAP3430 amd OMAP3630.

As per OMAP USBOTG specification, need to configure the USBOTG
to smart idle/standby or no idle/standby during data transfer and
force idle/standby when not in use to support retention and offmode.
By setting HWMOD_SWSUP_SIDLE and HWMOD_SWSUP_MSTANDBY flags, framework
will take care of configuring to no idle/standby when module is enabled
and force idle/standby when idled.

The OMAP watchdog timer IP blocks require a specific set of register
writes to occur before they will be disabled[1], even if the device
clocks appear to be disabled in the CM_*CLKEN registers.  In the MPU
watchdog case, failure to execute this reset sequence will eventually
cause the watchdog to reset the OMAP unexpectedly.

Previously, the code to disable this watchdog was manually called from
mach-omap2/devices.c during device initialization.  This causes the
watchdog to be unconditionally disabled for a portion of kernel
initialization.  This should be controllable by the board-*.c files,
since some system integrators will want full watchdog coverage of
kernel initialization.  Also, the watchdog disable code was not
connected to the hwmod shutdown code.  This means that calling
omap_hwmod_shutdown() will not, in fact, disable the watchdog, and the
goal of omap_hwmod_shutdown() is to be able to shutdown any on-chip
OMAP device.

To resolve the latter problem, populate the pre_shutdown pointer in
the watchdog timer hwmod classes with a function that executes the
watchdog shutdown sequence.  This allows the hwmod code to fully
disable the watchdog.

Then, to allow some board files to support watchdog coverage
throughout kernel initialization, add common code to mach-omap2/io.c
to cause the MPU watchdog to be disabled on boot unless a board file
specifically requests it to remain enabled.  Board files can do this
by changing the watchdog timer hwmod's postsetup state between the
omap2_init_common_infrastructure() and omap2_init_common_devices()
function calls.

Add support for categorizing and iterating over hardware IP blocks by
the "class" of the IP block.  The class is the type of the IP block:
e.g., "timer", "timer1ms", etc.  Move the OCP_SYSCONFIG/SYSSTATUS data
from the struct omap_hwmod into the struct omap_hwmod_class, since
it's expected to stay consistent for each class.  While here, fix some
comments.

The hwmod_class structures in this patch were designed and proposed by
Benoît Cousson <b-cousson@ti.com> and were refined in a discussion
between Thara Gopinath <thara@ti.com>, Kevin Hilman
<khilman@deeprootsystems.com>, and myself.

This patch uses WARN() lines that are longer than 80 characters, as
Kevin noted a broader lkml consensus to increase greppability by
keeping the messages all on one line.

Code should be able to #include any header file without the fear that
the header file will go allocating memory.  This is a coding style
issue, similar to commit 82e9bd58.
Move the existing hwmod data from .h files to .c files.

While here, convert "omap34xx" to "omap3xxx" in the hwmod files, since
most of these structures should be reusable across all OMAP3 chips.
