lib/genalloc: add parameter description to fix doc compile warning

Commit facfde5c4795 ("lib/genalloc.c: fix allocation of aligned buffer
from non-aligned chunk") added a new parameter 'start_addr' w/o
description for it. That causes some doc compile warning:

  lib/genalloc.c:649: warning: Function parameter or member 'start_addr' not described in 'gen_pool_first_fit'
  lib/genalloc.c:667: warning: Function parameter or member 'start_addr' not described in 'gen_pool_first_fit_align'
  lib/genalloc.c:694: warning: Function parameter or member 'start_addr' not described in 'gen_pool_fixed_alloc'
  lib/genalloc.c:729: warning: Function parameter or member 'start_addr' not described in 'gen_pool_first_fit_order_align'
  lib/genalloc.c:752: warning: Function parameter or member 'start_addr' not described in 'gen_pool_best_fit'

This fixes it by adding a parameter descriptions.
