ARM: lh7a40x: remove unmaintained platform support

lh7a40x has only been receiving updates for updates to generic code.
The last involvement from the maintainer according to the git logs was
in 2006.  As such, it is a maintainence burden with no benefit.

This gets rid of two defconfigs.

-README on the SDRAM Controller for the LH7a40X
-==============================================
-
-The standard configuration for the SDRAM controller generates a sparse
-memory array.  The precise layout is determined by the SDRAM chips.  A
-default kernel configuration assembles the discontiguous memory
-regions into separate memory nodes via the NUMA (Non-Uniform Memory
-Architecture) facilities.  In this default configuration, the kernel
-is forgiving about the precise layout.  As long as it is given an
-accurate picture of available memory by the bootloader the kernel will
-execute correctly.
-
-The SDRC supports a mode where some of the chip select lines are
-swapped in order to make SDRAM look like a synchronous ROM.  Setting
-this bit means that the RAM will present as a contiguous array.  Some
-programmers prefer this to the discontiguous layout.  Be aware that
-may be a penalty for this feature where some some configurations of
-memory are significantly reduced; i.e. 64MiB of RAM appears as only 32
-MiB.
-
-There are a couple of configuration options to override the default
-behavior.  When the SROMLL bit is set and memory appears as a
-contiguous array, there is no reason to support NUMA.
-CONFIG_LH7A40X_CONTIGMEM disables NUMA support.  When physical memory
-is discontiguous, the memory tables are organized such that there are
-two banks per nodes with a small gap between them.  This layout wastes
-some kernel memory for page tables representing non-existent memory.
-CONFIG_LH7A40X_ONE_BANK_PER_NODE optimizes the node tables such that
-there are no gaps.  These options control the low level organization
-of the memory management tables in ways that may prevent the kernel
-from booting or may cause the kernel to allocated excessively large
-page tables.  Be warned.  Only change these options if you know what
-you are doing.  The default behavior is a reasonable compromise that
-will suit all users.

-A typical 32MiB system with the default configuration options will
-find physical memory managed as follows.
-
-   node 0: 0xc0000000 4MiB
-           0xc1000000 4MiB
-   node 1: 0xc4000000 4MiB
-           0xc5000000 4MiB
-   node 2: 0xc8000000 4MiB
-           0xc9000000 4MiB
-   node 3: 0xcc000000 4MiB
-           0xcd000000 4MiB
-
-Setting CONFIG_LH7A40X_ONE_BANK_PER_NODE will put each bank into a
-separate node.
