This code was only used by 2430sdp, 3430sdp, and n900 development
boards.

The 2430sdp is already device tree only, and all the users of the
3430sdp and n900 development boards are already booting in device
tree mode, so we can drop the legacy smc91x support.

OMAP4, OMAP5 and DRA7 share a lot of common logic and data structures.
These have been enabled in the previous patches, however, this also
means that OMAP5 or DRA7 only builds also need to build OMAP4 logic.
Update to reuse OMAP4 logic.

This fixes the 'undefined reference to 'omap4_pm_init_early'' in
OMAP5 or DRA7 only builds.

The old 2420 based H4 is probably not used at all as 2420

We need to check for AM43XX without any omap4 or 5 related

Build AM43x power domain, clock domain and hwmod data.

Many of AM43x IP's and interconnects are similar as that in AM335x,
hence AM335x hwmod data is being reused with necessary changes.

Earlier the plan was to reuse AM335x specific PRCM code, but as AM43x
PRCM register layout is much similar to OMAP4/5, AM335x PRCM is
divorced and instead married with OMAP4/5 PRCM for AM43x.

AM335x and AM43x have most of the IP's and interconnect's similar.
Instead of adding redundant hwmod data, move interconnects and hwmod
similar between AM335x and AM43x to a common location. This helps in
reuse on AM43x.

AM335x interconnects that has difference and not present in AM43x are
not moved. ocp clock of those in l4_wkup is fed from a different source
for AM43x. Also pruss interconnect is different.

AM335x hwmod's that has difference other than prcm register offsets
(difference is in clocks of wkup_m3, control, gpio0, debugss and clock
domain of l4_hs, adc_tsc as compared to AM43x) and those that are not
present in AM43x are not moved.

For example, on a kernel image supporting multiple platforms, omap_init_drm

doesn't have a DSS block.

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+
