ARC: [axs101] Add support for AXS101 SDP (software development platform) The AXS10x platforms consist of a mainboard with peripherals, on which several daughter cards can be placed. The daughter cards typically contain a CPU and memory.

ARC: [axs101] support early 8250 uart Earlycon calculates UART clock as "BASE_BAUD * 16". In case of ARC "BASE_BAUD" is calculated dynamically in runtime, basically it is an alias to arc_early_base_baud(), which in turn just does "arc_base_baud/16". 8250 UART on AXS/SDP board uses 33.3MHz clock source which is set in "arc_base_baud" with this change. Additional compatibility string "snps,arc-sdp" is introduced as well because there're different flavours of AXS boards but they all share the same motherboard and so it's possible to re-use the same code for motherbord even if CPU daughterboard changes.
