[PATCH] riscv: increase COMMAND_LINE_SIZE value to 2048

From: Austin Kim <austin.kim at lge.com>

SoC people may send many parameters to configure the drivers via kernel 
command line. If COMMAND_LINE_SIZE is not enough, they may go through 
unexpected error.

To avoid the potential pain, we had better increase COMMAND_LINE_SIZE.
