ARC: [nsimosci] Unbork console
commit 61fb4bfc010b0d2940f7fd87acbce6a0f03217cb upstream.
Despite the switch to right UART driver (prev patch), serial console
still doesn't work due to missing CONFIG_SERIAL_OF_PLATFORM
Also fix the default cmdline in DT to not refer to out-of-tree
ARC framebuffer driver for console.
