Remove LYNX KDI remainders

The last board that used to set CONFIG_LYNXKDI has been removed in
commit 242836a893 ("powerpc: ppc4xx: remove pcs440ep support"),
doc/README.lynxkdi only talks about a MPC8260 board being supported,
and the mpc8260 support has been removed four years ago in commit
2eb48ff7a2 ("powerpc, 8260: remove support for mpc8260") already,
and common/lynxkdi.c only consists of an "#error" statement these
days, so it seems like the LYNX KDI code is dead code nowadays.
Let's remove it now.

-			   LYNX KDI SUPPORT
-
-		    Last Update: July 20, 2003
-=======================================================================
-
-This file describes support for LynuxWorks KDI within U-Boot. Support
-is enabled by defining CONFIG_LYNXKDI.
-
-
-LYNXOS AND BLUECAT SUPPORTED
-============================
-Both LynxOS and BlueCat linux KDIs are supported. The implementation
-automatically detects which is being booted. When you use mkimage
-you should specify "lynxos" for both (see target-specific notes).
-
-
-SUPPORTED ARCHITECTURE/TARGETS
-==============================
-The following targets have been tested:
-
--PowerPC  MPC8260ADS
-
-
-FILES TO LOOK AT
-================
-include/lynxkdi.h    -defines a simple struct passed to a kdi.
-common/lynxkdi.c     -implements the call to the kdi.
-common/cmd_bootm.c   -top-level command implementation ("bootm").
-
-
-====================================================================
-TARGET SPECIFIC NOTES
-====================================================================
-
-MPC8260ADS
-===========
-The default LynxOS and BlueCat implementations require some
-modifications to the config file.
-
-Edit include/configs/MPC8260ADS.h to use the following:
-
-#define CONFIG_SYS_IMMR	0xFA200000
-#define CONFIG_SYS_BCSR	0xFA100000
-#define CONFIG_SYS_BR1_PRELIM	0xFA101801
-
-When creating a LynxOS or BlueCat u-boot image using mkimage,
-you must specify the following:
-
-Both:    -A ppc -O lynxos -T kernel -C none
-LynxOS:  -a 0x00004000 -e 0x00004020
-BlueCat: -a 0x00500000 -e 0x00507000
-
-To pass the MAC address to BlueCat you should define the
-"fcc2_ether_addr" parameter in the "bootargs" environment
-variable. E.g.:
-
-==> setenv bootargs fcc2_ether_addr=00:11:22:33:44:55:66
