Add the ability to not report an I2C POST error for a set of given I2C
addresses on bootup.  This is useful for cases when a device may or may
not be present, and neither case is considered an error.  For example:

- Some form factors such as XMC and Compact PCI Express have an I2C
  EEPROM whose address changes based on geographical address.  Eg
  installed in one slot its EEPROM address is, 0x50, in another its
  0x51, etc.  This allows multiple devices to have their EEPROMs present
  on the same I2C bus.  Thus the I2C devices present for an XMC or
  CPCIe card depend on if and where other cards are installed in the
  same system.

- Some cards have optional I2C devices.  Eg one hardware build
  configuration has different I2C devices than another and software
  can't determine if the optional device should be present or not.

- Some cards have optional daughtercards with I2C devices on them.

- I2C EEPROMs address range depends on their size.  Its possible to
  support differently size EEPROMs by only probing the EEPROM's base
  address and ignoring the other addresses that are impacted by its
  size.

A new CONFIG_SYS_POST_I2C_IGNORES define has been added which specifies
a list of I2C addresses for the I2C POST to ignore.

According to the I2C specification device address 0 is the "general call
address", ie a broadcast address.  The I2C specification states that the
format of a general call uses at least 2 bytes, which U-Boot's probing
routine does not adhere to.

Not probing device address 0 will prevent possible issues with devices
that accept general calls.  Additionally, this change shouldn't reduce
POST coverage since each I2C device should still be accessed via its
own, unique address.

Some U-Boot images for X-ES boards support multiple products in the same
family.  For example, the XPedite5370, XPedite5371, and XPedite5372 are
similar enough that one U-Boot image can work on all 3 cards.  To make it
clear that a U-Boot image can work on boards of the same family, rename
the boards with the least significant digit of 'x'.

While we're at it, change the board config file and make targets to be
lowercase.

Also change the default uImage and fdt filenames to "board.uImage" and
"board.dtb" to be more generic.

Add board_flash_wp_on() to check a pca9557 gpio pin to see
if non-volatile memory write protection is enabled.

Previously, write protected NOR flashes would fail initialization which
resulted in a bootup error such as:

 ...
 DTT:   53 C local / 64 C remote (adt7461@4c)
 DTT:   54 C local (ds1621@48)
 FLASH: Executed from FLASH1
 POST memory PASSED
 FLASH: ## Unknown FLASH on Bank 1 - Size = 0x00000000 = 0 MB
 ## Unknown FLASH on Bank 2 - Size = 0x00000000 = 0 MB
 *** failed ***
 ### ERROR ### Please RESET the board ###

With this patch, NOR flash initialization is skipped:

 ...
 DTT:   53 C local / 64 C remote (adt7461@4c)
 DTT:   54 C local (ds1621@48)
 FLASH: Executed from FLASH1
 POST memory PASSED
 FLASH: Uninitialized - Write Protect On
 L2:    1024 KB enabled
 NAND:  1024 MiB
 ...

Note that flash related commands such as flinfo and saveenv will error
out when flash write protection is enabled.
