Add the ARM PLL controller which comes standard with the Cortex-A9 found
on the BCM63138 SoCs. This is the same controller as the one found in
the Broadcom iProc architecture, however, we have a separate compatible
string to indicate the integration difference, since the hardware is
different.

The NAND controller is a child node of the UBUS (legacy) bus, not the
AXI (new) bus, re-parent the NAND controller node accordingly. This was
a mistake introduced by a failed merge of this NAND node with other
changes (PMB).

Add a "brcm,bcm6328-timer" and "syscon-reboot" nodes to allow the
generic syscon-reboot driver to reset a BCM63138 SoC.

Update bcm63138.dtsi with the following:
- enable-method for both CPU nodes
- brcm,bcm63138-bootlut node
- resets properties to point to the correct PMB controller to release
the secondary CPU from reset

Add the two BCM63138 PMB busses nodes found on this System-on-a-Chip as
described in their corresponding binding document.

The L2 cache properties were completely off with respect to what the
hardware is configured for. Fix the cache-size, cache-line-size and
cache-sets to reflect the L2 cache controller we have: 512KB, 16 ways
and 32 bytes per cache-line.

all other nodes in bcm63138.dtsi use "interrupts", this had to be just a typo
which never got noticed, even it may have quite some consequences.

Add a very minimalistic BCM63138 Device Tree include file which
describes the BCM63138 SoC with only the basic set of required
peripherals:
- Cortex A9 CPUs
- ARM GIC
- ARM SCU
- PL310 Level-2 cache controller
- ARM TWD & Global timers
- ARM TWD watchdog
- legacy MIPS bus (UBUS)
- BCM6345-style UARTs (disabled by default)
Since the PL310 L2 cache controller does not come out of reset with
correct default values, we need to override the 'cache-sets' and
'cache-size' properties to get its geometry right.
