platform/chrome: lightbar: Use flexible array member

Variable arrays should be defined as [], not [0], otherwise
the kernel complains:

memcpy  : detected field-spanning write (size 9) of single field "param->set_program_ex.data" at drivers/platform/chrome/cros_ec_lightbar.c:603 (size 0)

Fixes: 9600b8bdbf ("platform/chrome: lightbar: Add support for large sequence")
