arm: Remove unnecessary of_platform_populate with default match table

After patch "of/platform: Add common method to populate default bus",
it is possible for arch code to remove unnecessary callers of
of_platform_populate with default match table.

platform: Remove most references to platform_bus device

A number of board files in arch/arm and arch/unicore32
explicitly reference platform_bus device as a parent
for new platform devices.

This is unnecessary, as platform device API guarantees
that devices with NULL parent are going to by adopted
by the mentioned "root" device.

This patch removes or replaces with NULL such references.

In preparation for future SoCs, move kona_l2_cache_init() from board

can make use of it. Also change the return type to "void", since we
never look at the return code anyway.

This patch renames a few symbols that needlessly used "11351" rather

the family of boards is more properly referred to as "bcm281xx".

ARM: bcm: provide common arch init for DT clocks

With arch/arm calling of_clk_init(NULL) and clocksource_of_init()
this is no longer needed. The former is useful because we can make
use of dummy fixed clocks for drivers until the bcm281xx common
clock driver is ready.

ARM: bcm: Make secure API call optional

The current bcm_kona_smc_init function throws a BUG_ON if there's no SMC

Since secure API access is optional depending the chip configuration,
fix this by allowing the rest of the code to run even if there's no SMC
device node defined

ARM: DT: binding fixup to align with vendor-prefixes.txt (drivers)

[ this is a follow-up to this discussion:
http://archive.arm.linux.org.uk/lurker/message/20130730.230827.a1ceb12a.en.html ]
This patchset renames all uses of "bcm," name bindings to
"brcm," as they were done prior to knowing that brcm had
already been standardized as Broadcom vendor prefix
(in Documentation/devicetree/bindings/vendor-prefixes.txt).
This will not cause any churn on devices because none of
these bindings have made it into production yet.
