Nothing outside mach-tegra uses this file, so there's no need for it to
be in <mach/>.

Since uncompress.h and debug-macro.S remain in include/mach, they need
to include "../../iomap.h" becaue of this change. uncompress.h will soon
be deleted in later multi-platform/single-zImage patches. debug-macro.S
will need to continue to include this header using an explicit relative
path, to avoid duplicating the physical->virtual address mapping that
iomap.h dictates.

The ports are used as follows:
UART1/A: Routed to debug dongle
UART2/B: GPS
UART3/C: Bluetooth
UART4/D: Routed to debug dongle
UART5/E: Not connected

The debug dongle has jumpers to connect either UART1/A or UART4/D to
the DB-9 connector. UART1/A is typically used on Cardhu, and is the option
we assume here.

For now, only enable UART1/A, and explicitly disable all other ports.

The explicit disable prevents the message "of_serial 70006040.serial:
no clock-frequency property set" being printed during boot.

Enabling the other ports requires their clocks to be enabled, or accesses
to the registers will hang. At present, this requires adding entries into
board-dt-tegra30.c's tegra_dt_clk_init_table[]. Lets punt on that and wait
for the common clock bindings to set this all up, although that will also
requiring adding clock support to 8250.c.

While we're at it, fix board-dt-tegra30.c to enable the correct clock for
the debug UART. We got away with this before, because the bootloader already
enabled it.

board-dt-tegra*.c should support any board using Tegra when booted using
device tree. Instead of explicitly listing all the supported boards,
which requires a kernel change for each new board, list the supported SoC
model instead.

Note that the board files do currently have explicit support for setting
up each board's pinmux. However, it's fairly likely that at least the
basic devices on any new board will work just fine as set up by the boot-
loader, and the pinmux data should be moving into device tree soon anyway.

Add support for tegra30 SoC. This includes a device tree compatible type for
this SoC ("nvidia,tegra30") and adds L2 cache initialization for this new SoC.
The clock framework is still missing, which prevents most drivers from working.
The basic IRQs are the same, so remove the dependency on
CONFIG_ARCH_TEGRA_2x_SOC.
