SoC new development for tegra SoCs, mostly tegra30 core support.
It also includes one stray bugfix that was misapplied (should have been
in soc-drivers), but it went out to the stable branches before I noticed
so I've left it in.

Minor fixes that weren't urgent enough to go into 3.3. The two paz00
patches are in mainline already but got merged after the branch point
for this branch, so they're duplicated. I also ended up merging in
rmk/for-armsoc into this later on to fix a bug introduced by it, so it's
included but it's not the base of this branch.

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.

Even if cards supports 1.8V I/O voltage those should anyway be
initialized at 3.3V I/O according to (e)MMC, SD and SDIO specs.
Some eMMC and embedded SDIO devices are able to be initialized
at 1.8V as well, but it is better to be safe.
Do note that initialization in this context means that the card
has been completely powered off, otherwise the card will remain
at the last I/O voltage level that were negotitiated.
Due to the above being taken care of the suspend/resume issues
for UHS-I SD-cards has been fixed.

This is because of a 64k request with a max_req_size of 64k-1 bytes.
The following patch fixes the problem by limiting the max_blk_count
such that max_blk_count * max_blk_size == max_req_size. I couldn't
pursuade the compiler to emit a shift instead of a div without encoding

On i.MX53 we have to write a special SDHCI_CMD_ABORTCMD to the
SDHCI_TRANSFER_MODE register during a MMC_STOP_TRANSMISSION
command. This works for SD cards. However, with MMC cards
the MMC_SET_BLOCK_COUNT command is used instead, but this
needs the same handling. Fix MMC cards by testing for the
MMC_SET_BLOCK_COUNT command aswell. Tested on a custom i.MX53
board with a Transcend MMC+ card and eMMC.
The kernel started used MMC_SET_BLOCK_COUNT in 3.0, so this
is a regression for these boards introduced in 3.0; it should
go to 3.0/3.1/3.2-stable.

A recent commit "mmc: core: Use delayed work in clock gating framework"
(597dd9d79c) introduced a default 200ms delay before clock gating
actually takes place. This means that every time an MMC interface
becomes idle it first stays on for 200ms before gating its clock. This
leads to increased power consumption and is therefore a clear regression.
This patch restores the original behaviour by setting the default delay
to 0. Users prioritising throughput over power efficiency can still
modify the delay via sysfs.

There's now core code which falls back to global CODEC operations for
DAI calls that needs to be able to tell if it's dealing with a CPU or
CODEC DAI and given the small number of DAIs in a typical system and
overall memory usage pattern saving a pointer per DAI is really not
worth the effort.
