[Buildroot] [PATCH v2] synopsys/hsdk: Linux Boot log cleanup

[Evgeniy Didin]

This patch removes duplicate messages in Linux log on HSDK board.
For HSDK board we setup bootargs via device tree,
see https://elixir.bootlin.com/linux/latest/source/arch/arc/boot/dts/hsdk.dts#L25
"console=ttyS3" was mistakenly placed in u-boot bootargs which are
appended to Kernel bootargs in case of using buildin .dtb.

Before patch log is like:
------------------------8<-------------------------------------
mmc_host mmc0: Bus speed (slot 0) = 50000000Hz (slot req 25000000Hz,...
mmc_host mmc0: Bus speed (slot 0) = 50000000Hz (slot req 25000000Hz,...
mmc0: new SDHC card at address 59b4
mmc0: new SDHC card@address 59b4
blk_queue_max_segment_size: set to minimum 8192
blk_queue_max_segment_size: set to minimum 8192
------------------------>8-------------------------------------

After patch log is like:
------------------------8<-------------------------------------
mmc_host mmc0: Bus speed (slot 0) = 50000000Hz (slot req 25000000Hz,...
mmc0: new SDHC card at address 59b4
blk_queue_max_segment_size: set to minimum 8192
------------------------8<-------------------------------------
