This patch creates an l4_wkup interconnect for AM43xx, and moves some of
the generic peripherals under it. System control module nodes are moved
under this new interconnect also, and the SCM clock layout is changed
to use the renamed SCM nodea as the clock provider.

Added a new compatible string "ti,am437x-ocp2scp" for OCP2SCP module.
This is needed since except for the OCP2SCP used in AM437x, SYNC2 value
in OCP2SCP TIMING should be changed whereas the default value is sufficient
in AM437x.

OMAP4/5 has been (ab)using the gic_arch_extn to provide
wakeup from suspend, and it makes a lot of sense to convert
this code to use stacked domains instead.

This patch does just this, updating the DT files to actually
reflect what the HW provides.

BIG FAT WARNING: because the DTs were so far lying by not
exposing the WUGEN HW block, kernels with this patch applied
won't have any suspend-resume facility when booted with old DTs,
and old kernels with updated DTs won't even boot.

On a platform with this patch applied, the system looks like
this:

Whenever Suspend PHY bit is set on AM437x devices,
USB will not work due to Set EP Configuration command
always failing.

This was only found after a recent commit 2164a476 (usb:
dwc3: set SUSPHY bit for all cores, which will be merged
for v3.19) added a missing *required* step to dwc3
initialization. Synopsys Databook requires that we enable
Suspend PHY bit after initialization but that, unfortunately,
breaks AM437x.

Populate uarts, timers, rtc, wdt, gpio, i2c, spi, cpsw & pwm nodes.

Reason for adding these nodes early - hwmod code required address
space of peripherals corresponding to these nodes (as address space
details are removed from hwmod database).

uart0, timers - 1 & 2 and synctimer were already present, so here the
remaining uarts & timers are added.

All properties as per the existing binding has been added for uart,
timer, rtc, wdt & gpio. Even though that was not the current scope
of work, felt adding those would reduce or require no effort later
to get these peripherals working.

For i2c, spi, cpsw & pwm - only the properties that were sure to be
correct has been added (main intention is to make hwmod happy and
avoid any later modification to here added properties).

While at it add "ti,hwmod" property to already existing nodes.
