[ARM] Remove EPXA10DB machine support
EPXA10DB seems to be uncared for: - the "PLD" code has never been merged - no one has reported that this platform has been broken since at least 2.6.10 - interest seems to have dried up around March 2003. Therefore, remove EPXA10DB support. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

39 This is the driver for Altera's ether00 ethernet mac IP core. Say
40 Y here if you want to build support for this into the kernel. It
41 is also available as a module (say M here) that can be inserted/
42 removed from the kernel at the same time as the PLD is configured.
43 If this driver is running on an epxa10 development board then it
44 will generate a suitable hw address based on the board serial
45 number (MTD support is required for this). Otherwise you will
46 need to set a suitable hw address using ifconfig.
