arc770: Remove arc770 target

The arc700 target is not booting up since some time, see here:
https://github.com/foss-for-synopsys-dwc-arc-processors/toolchain/issues/400

It looks like there is a problem in the toolchain when using glibc.

Currently no one is working on fixing this problem, remove the target
instead. This target also does not have many users we are aware of.

If someone wants to have this target back, feel free to add a fixed
version of this target again.

-From: Alexey Brodkin <abrodkin@synopsys.com>
-Date: Wed, 27 Jul 2016 11:33:14 +0300
-Subject: [PATCH] stmmac: Disable frame filtering completely
-
-For some [still unknown] reason in ARC SDP boards
-DW GMAC doesn't enter promiscuous mode if eth0 gets
-added to the br-lan interface before Ethernet PHY finishes
-autonegotiation (PHY gets reset on DW GMAC start).
-
-As a work-around we completely disable frame filtering
-in GMAC hardware which gives us working bridge that consists
-of eth0 and wlan0 (USB Wi-Fi dongle). I.e. we finally have
-working "Dumb AP" setup made of ARC AXS10x boards.
