ARM: tegra: move CONFIG_TEGRAnn

<asm/arch-tegra/tegra.h> needs to use CONFIG_TEGRA* to conditionalize
some definitions, since some modules moved between generations. Move
the definition of CONFIG_TEGRAnn to a header that's included earlier,
so that it's set by the time tegra.h needs to use it.

ARM: tegra: fix pmc_pwrgate_timer_mult register definition

Register pmc_pwrgate_timer_mult has a different layout on Tegra114 and
Tegra124. Reflect this in pmc.h.

Also, simply write the whole of the register in start_cpu() rather than
doing a read-modify-write; the register is simple enough that the code
can easily construct the entire desired value.

ARM: tegra: simplify halt_avp()

In order to completely halt the AVP processor, we should simply write
FLOW_MODE_STOP without any extra options that allow wakeup. Amend the
code to do this.

I believe that enabling FIQ_1 and IRQ_1 allow the CPU to be awoken by
interrupts. We don't want this; if later SW wishes to use the AVP, it
should be reset and booted from scratch.

Related, the bits that were previously IRQ_1 and FIQ_1 have a slightly
different definition starting with Tegra114, so the values we're
writing don't entirely make sense there anyway.

ARM: tegra: set CONFIG_SYS_USB_EHCI_MAX_ROOT_PORTS

Tegra's EHCI controllers only have a single PORTSC register. Configure
U-Boot to know this. This prevents e.g. ehci_shutdown() from touching
non-existent registers.

ARM: tegra: rework boot scripts

Update the common Tegra boot scripts in the default environment to

a) Make use of the new "test -e" shell command to avoid some error
   messages.

b) Allow booting using the sysboot command and extlinux.conf. This
   allows easy creation of boot menus, and provides a simple interface
   for distros to parameterize/configure the boot process.

OMAP3: igep00x0: Enable required clocks for GPIO that are used.

Enable required clocks for GPIO to fix a boot issue introduced by commit
f33b9bd3984fb11e1d8566a866adc5957b1e1c9d (arm: omap3: Enable clocks for
peripherals only if they are used).

Without this patch the u-boot freezes after the following messages

  OMAP36XX/37XX-GP ES1.2, CPU-OPP2, L3-200MHz, Max CPU Clock 1 Ghz
  IGEPv2 + LPDDR/NAND
  I2C:   ready
  DRAM:  512 MiB
  NAND:  512 MiB
  MMC:   OMAP SD/MMC: 0

Diving into the issue, the sequence that produces the u-boot freezes is

  setup_net_chip
   |--> gpio_direction_out
         |--> _set_gpio_dataout
               |--> __raw_writel

To avoid this we just need enable the clocks for GPIOs that are used, but it
would be interesting implement a mechanism to protect these situations and
make sure that the clock is enabled when we request a GPIO.

at91sam9263ek: add mmc support

Add support for using the Atmel MCI driver on at91sam9263ek.
This change is modeled after the existing at91sam9260ek support.

Please note that this hooks up slot1 (MCI1) for SD. Not both.

Tested with at91bootstrap and u-boot on dataflash in slot 0
and fat-formatted 8GB SDHC in slot 1 on first revision
at91sam9263ek (which must use dataflash in slot0 to boot).

CONFIG_ATMEL_MCI_PORTB not tested.

I have observed timeouts on a cubietruck.

The increase to 40ms is completely arbitrary and Works For Me(tm). I
couldn't find a good reference for how long you are supposed to wait,
although googling around it seems like tens of ms rather than single
digits is more common. I don't think there is any harm in waiting a bit
longer.
