arc: add AXS101 board support
AXS101 is a new generation of devlopment boards from Synopsys that houses ASIC with ARC700 and lots of DesignWare peripherals: * DW APB UART * DW Mobile Storage (MMC/SD) * DW I2C * DW GMAC Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com> Cc: Vineet Gupta <vgupta@synopsys.com> Cc: Francois Bedard <fbedard@synopsys.com> Cc: Wolfgang Denk <wd@denx.de> Cc: Heiko Schocher <hs@denx.de>
