ARM: tegra: support T33 SKU of Tegra30

Make U-Boot aware of the T33 SKU of Tegra30, and treat it identically
to any other Tegra30.

An alternative would be to simply remove the SKU checking from
tegra_get_chip_type(); most use of the value most likely simply wants
to know the current chip, not the specific SKU. Or, the function could
be split into separate tegra_get_chip() and tegra_get_sku() for the
cases where differentiation really is required.

I wonder whether tegra_get_chip_type() should printf() whenever any
unkown chip/SKU is found, although perhaps the function is called so
early that the printf() wouldn't actually make it to the UART anyway.

Tegra: Restore cp15 VBAR _start vector write for ARMv7

A start vector fix was added by AneeshV for OMAP4 (commit 0d479b53),
and caused the old monilithic Tegra builds to hang due to an undefined
instruction trap. Previously, the code needed to run on both the
AVP (ARM7TDI) and A9, and the AVP doesn't have a CP15 register.
I corrected this in commit 6d6c0bae w/#ifndef CONFIG_TEGRA, but
now that we use SPL, and boot the AVP w/o any ARMv7 code, I can
revert my change, and make Aneesh's change apply to Tegra.

Tegra: Split tegra_get_chip_type() into soc & sku funcs

As suggested by Stephen Warren, use tegra_get_chip() to return
the pure CHIPID for a Tegra SoC (i.e. 0x20 for Tegra20, 0x30 for
Tegra30, etc.) and rename tegra_get_chip_type() to reflect its true
function, i.e. tegra_get_chip_sku(), which returns an ID like
TEGRA_SOC_T25, TEGRA_SOC_T33, etc.

The ARM errata 742230 - "ARM errata: DMB operation may be faulty" is
claimed for Cortex-A9 (r1p0..r2p2).  Though i.MX6 uses a newer revision
than r2p2, we are seeing a reboot failure on i.MX6 SMP build that can be
fixed by applying the workaround for this errata.  So for safety, let's
define CONFIG_ARM_ERRATA_742230 to enable the workaround on i.MX6.
