This patch updates the common platform files with TI816X support.

The approach taken in this patch is to add TI816X as part of OMAP3 variant where
the cpu class is considered as OMAP34XX and the type is TI816X. This means, both
cpu_is_omap34xx() and cpu_is_ti816x() checks return success on TI816X.

A kernel config option CONFIG_SOC_OMAPTI816X is added under OMAP3 to include
support for TI816X build.

The new init_early hook happens at the end of setup_arch,
which is too early for kzalloc. However, there's no need
to call omap_serial_early_init that early, so fix this
by setting it up as a core_initcall.

The ptrace debug information register was advertising breakpoint and
watchpoint resources for unsupported debug architectures. This meant
that setting breakpoints on these architectures would appear to succeed,
although they would never fire in reality.

This patch fixes the breakpoint slot probing so that it returns 0 when
running on an unsupported debug architecture.

Reading baseline CP14 registers, other than DBGDIDR, when the OS Lock

rmk says: "You might as well make OABI_COMPAT depend on !THUMB2_KERNEL.
OABI userland is useless without FPA support."

nwfpe doesn't work with Thumb-2 anyway and will probably never get

Since tail is the previous fp - 1, we need to compare the new fp with tail + 1
to ensure that we don't end up passing in the same tail again, in order to
avoid a potential infinite loop in the perf interrupt handler (which has been
observed to occur).  A similar fix seems to be needed in the OProfile code.

OMAP2 (armv6) and MX3 turn off support for the V6K instructions, which
when they include support for SMP kernels means that the resulting
kernel is unsafe on SMP and can result in corrupted filesystems as we
end up using unsafe bitops.

Re-enable the use of V6K instructions on such kernels, and let such
kernels running on V6 CPUs eat undefined instruction faults which will
be much safer than filesystem corruption.  Next merge window we can fix
this properly (as it requires a much bigger set of changes.)

omap1: DMA: move LCD related code from plat-omap to mach-omap1

The code introduced by this patch didn't consider any other CPUs but OMAP1510,
which rendered OMAP310 -- which has the same LCD controller -- non-working. Use
cpu_is_omap15xx() instead of cpu_is_omap1510() to squash this issue.

This patch fixes a wrongly used lcd enable pin.

The Devkit8000 uses twl4030_ledA configured as output gpio only for
the lcd enable line. twl4030_gpio.1 is used through the generic
gpio functions while ledA is used via low level twl4030 calls.

This patch removes the low level calls and use the generic gpio functions
for initialization and use of ledA. This patch also fixes a bug where the
lcd would not power down when blanking.

Further this patch fixes an indentation issue. The comment line uses
eight whitespace and is replaced with a hard tab.

gpio_request + gpio_direction_output are replaced with gpio_request_one.
The return value of gpio_request_one is used to set the value of the
gpio to -EINVAL when unsuccessful, so that gpio_is_valid can detect the
unsuccessful request. But already successful requested gpios are not freed.
