sh: Kill off long-dead HD64465 cchip support.
This code has been dead for many years. The last update it received was in 2003 in order to update it for the driver model changes, though it had already been in disarray and unused before that point. The only boards that ever used this chip have not had users in many years either, so it is finally safe to just kill it off and move on with life. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2 * Device driver for the PCMCIA controller module of the
3 * Hitachi HD64465 handheld companion chip.
4 *
5 * Note that the HD64465 provides a very thin PCMCIA host bridge
6 * layer, requiring a lot of the work of supporting cards to be
7 * performed by the processor. For example: mapping of card
8 * interrupts to processor IRQs is done by IRQ demuxing software;
9 * IO and memory mappings are fixed; setting voltages according
10 * to card Voltage Select pins etc is done in software.
11 *
12 * Note also that this driver uses only the simple, fixed,
13 * 16MB, 16-bit wide mappings to PCMCIA spaces defined by the
14 * HD64465. Larger mappings, smaller mappings, or mappings of
15 * different width to the same socket, are all possible only by
16 * involving the SH7750's MMU, which is considered unnecessary here.
17 * The downside is that it may be possible for some drivers to
18 * break because they need or expect 8-bit mappings.
19 *
20 * This driver currently supports only the following configuration:
21 * SH7750 CPU, HD64465, TPS2206 voltage control chip.
