powerpc: ppc4xx: remove JSE board support

This has not been converted to Generic Board, so should be removed.
(See doc/README.generic-board for details.)

-JSE Configuration Details
-
-Memory Bank 0 -- Flash chip
----------------------------
-
-0xfff00000 - 0xffffffff
-
-The flash chip is really only 512Kbytes, but the high address bit of
-the 1Meg region is ignored, so the flash is replicated through the
-region. Thus, this is consistent with a flash base address 0xfff80000.
-
-The placement at the end is to be consistent with reset behavior,
-where the processor itself initially uses this bus to load the branch
-vector and start running.
-
-On-Chip Memory
---------------
-
-0xf4000000 - 0xf4000fff
-
-The 405GPr includes a 4K on-chip memory that can be placed however
-software chooses. I choose to place the memory at this address, to
-keep it out of the cachable areas.
-
-
-Memory Bank 1 -- SystemACE Controller
--------------------------------------
-
-0xf0000000 - 0xf00fffff
-
-The SystemACE chip is along on peripheral bank CS#1. We don't need
-much space, but 1Meg is the smallest we can configure the chip to
-allocate. We need it far away from the flash region, because this
-region is set to be non-cached.
-
-
-Internal Peripherals
---------------------
-
-0xef600300 - 0xef6008ff
-
-These are scattered various peripherals internal to the PPC405GPr
-chip.
-
-SDRAM
------
-
-0x00000000 - 0x07ffffff  (128 MBytes)
