This board is working with device tree based booting so there should
not be any need to keep the legacy booting support around. People
using this board can boot it with appended DTB with existing bootloader.

By removing the 3517 legacy booting support we can get a bit closer to
making all of omap3 boot in device tree only mode.

Commit 21278aea ("ARM: use menuconfig for sub-arch menus") improved
the sub-arch menus, but accidentally caused new warnings for omap1.
This was because the commit added a menu entry around config ARCH_OMAP
bool entry where the menu had depends on ARCH_MULTI_V6 || ARCH_MULTI_V7.

As ARCH_OMAP is shared between omap1 and omap2plus, let's fix the
issue by defining ARCH_OMAP in the shared plat-omap/Kconfig.

A number of configurations spit out warnings similar to:

warning: (SOC_IMX6 && SOC_VF610 && ARCH_OMAP4) selects PL310_ERRATA_588369 which has unmet direct dependencies (CACHE_L2X0)
warning: (SOC_IMX6 && SOC_VF610 && ARCH_OMAP4) selects PL310_ERRATA_727915 which has unmet direct dependencies (CACHE_L2X0)

Clean up the dependencies here:
* PL310 symbols should only be selected when CACHE_L2X0 is enabled.
* Since the cache-l2x0 code detects PL310 presence at runtime, and we will
  eventually get rid of CACHE_PL310, surround these errata options with an
  if CACHE_L2X0 conditional rather than repeating the dependency against
  each.

Commit d941f86f ("ARM: l2c: AM43x: add L2 cache support") enabled
the L2 cache support for the am43xx SoC, but caused a build regression
when the driver for that cache controller is disabled:

arch/arm/mach-omap2/built-in.o: In function `am43xx_init_early':
:(.init.text+0xb20): undefined reference to `omap_l2_cache_init'

This did not happen for OMAP4, which has the same call, but enables
the l2x0 driver unconditionally. We could do the same thing for
am43xx, but it seems better to allow turning it off and make the
code work in either case.

This adds an inline wrapper for omap_l2_cache_init for the disabled
case, and removes the 'select' from OMAP4 so it becomes a user
visible option.
