[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>
