p1022ds: allow for board-specific ngPIXIS functions

The ngPIXIS is an FPGA used on the reference boards of most Freescale PowerPC
SOCs. Although programming the ngPIXIS is mostly standard on all boards that
have it, the P1022DS is unique in that the ngPIXIS needs to be programmed in
"indirect" mode whenever the video display (DIU) is active.

To support indirect mode, and to make it easier to support other quirks on
future reference boards, the low-level ngPIXIS functions are all marked as
weak, so that board-specific code can override any of them. We take advantage
of this feature on the P1022DS, so that we can properly reset the board when
the DIU is active.

fsl: update CRC after setting EEPROM identifier

The "mac id" command is used to initialize the EEPROM data to a specific
format, but it was not updating the CRC. This didn't cause any real
problems, because writing the data to the EEPROM will always update the
CRC anyway, but it did result in a bogus CRC warning.

Switch from archive libraries to partial linking

Before this commit, weak symbols were not overridden by non-weak symbols
found in archive libraries when linking with recent versions of
binutils. As stated in the System V ABI, "the link editor does not
extract archive members to resolve undefined weak symbols".

This commit changes all Makefiles to use partial linking (ld -r) instead
of creating library archives, which forces all symbols to participate in
linking, allowing non-weak symbols to override weak symbols as intended.
This approach is also used by Linux, from which the gmake function
cmd_link_o_target (defined in config.mk and used in all Makefiles) is
inspired.

The name of each former library archive is preserved except for
extensions which change from ".a" to ".o". This commit updates
references accordingly where needed, in particular in some linker
scripts.

This commit reveals board configurations that exclude some features but
include source files that depend these disabled features in the build,
resulting in undefined symbols. Known such cases include:
- disabling CMD_NET but not CMD_NFS;
- enabling CONFIG_OF_LIBFDT but not CONFIG_QE.

fsl: add support for NXID v1 EEPROM format

Freescale application note AN3638 describes an update to the NXID format,
which stores MAC addresses and related data on an on-board EEPROM. The new
version adds support for up to 23 MAC addresses, instead of just 8. Since
the initial implementation of NXID had a "0" in the 'version' field, this
new version is called "v1".

Boards that are shipped with EEPROMs in the NXID v1 format should define
CONFIG_SYS_I2C_EEPROM_NXID_1 instead of CONFIG_SYS_I2C_EEPROM_NXID.

fsl: verify writes to the MAC address EEPROM

Update the code which writes to the on-board EEPROM so that it can detect if
the write failed because the EEPROM is write-protected. Most of the 8xxx-class
Freescale reference boards use an AT24C02 EEPROM to store MAC addresses and
similar information. With this patch, if the EEPROM is protected, the
"mac save" command will display an error message indicating that the write
has not succeeded.
