ARCv3:HS6x_haps: change RAM base to address 0

New FPGA images are now built with DDR mapped to address 0,
update the LINUX_RAM_BASE and LINUX_LINK_BASE in default
configs for arc64 and create new haps_hs6x.dts and
haps_hs6x_idu.dts.

Same as commit a3e8772 ("ARCv3:HS5x_haps: change RAM base to address 0")
but for hs6x.
