Large EEPROMs, e.g. 24lc32, need 2 byte to address the internal memory.
These devices require that the high byte of the internal address has to be
written first.
The mxs_i2c driver currently writes the address' low byte first.

The following patch fixes the byte order of the internal address that should
be written to the I2C device.

Other then being very weird, this code was also wrong.
For example, say I set speed to 100K. I'll read back the speed
as 85937. But the speed is really 85937.5, so we I reset
the speed to 85937, I'll get 73660.7. After a couple of transactions
my speed is now exactly 68750 so it will remain there.

When Trimslice is booted from serial flash, the boot ROM does this, so
U-Boot doesn't need to. However, booting from the SD slot for recovery
purposes, the boot ROM does not set up the pinmux for serial flash. Add
code to U-Boot to set this up, so that an SD-based recovery U-Boot image
can upgrade the U-Boot in serial flash.

Instead of initializing USB as soon as bootcmd is executed, defer it
until the first boot device that (potentially in the case of network)
uses USB is scanned. This avoids initializing USB when booting from MMC,
so speeds that up.

Place the list of searched boot devices, file-system types, boot file
locations/prefixes, and boot script names into variables. This allows
the user to override them directly (e.g. to change boot order, or select
the specific values they use) without having to edit the main bootcmd
and script_boot variables.

The default boot order is changed from USB, MMC, DHCP to MMC, USB, DHCP.
This speeds up the typical MMC boot case. People who want USB boot can
now edit variable boot_targets appropriately.

Also, reformat BOOTCMDS_COMMON to fit within 80 columns.

Potential future enhancements might be:
* Allow boards to specify which of bootcmd_mmc0/... should be defined,
  based on the HW they contain.
* Allow boards to influence the order that the boot targets are added
  into the boot_targets variable.

Tegra's boot ROM supports a mode whereby code may be downloaded and flash
programmed over a USB connection. On dev boards, this is typically entered
by holding down a "force recovery" button and resetting the CPU. However,
not all boards have such a button (one example is the Compulab Trimslice),
so a method to enter RCM from software is useful.

This change implements the command "enterrcm" to do this, and enables it
for all Tegra boards by default. Even on boards other than Trimslice,
controlling this over a UART may be useful, e.g. to allow simple remote
control without the need for mechanical button actuators, or hooking up
relays/... to the button.

The PI4 GPIO is used on Tamonten to reset carrier board peripherals.
Power sequencing hardware on the carrier pulls the reset low before
