resource/docs: Fix new kernel-doc warnings

Browse Source 
The first group of warnings is caused by a "/**" kernel-doc notation
marker but the function comments are not in kernel-doc format.
Also add another error return value here.

  ../kernel/resource.c:337: warning: Function parameter or member 'start' not described in 'find_next_iomem_res'
  ../kernel/resource.c:337: warning: Function parameter or member 'end' not described in 'find_next_iomem_res'
  ../kernel/resource.c:337: warning: Function parameter or member 'flags' not described in 'find_next_iomem_res'
  ../kernel/resource.c:337: warning: Function parameter or member 'desc' not described in 'find_next_iomem_res'
  ../kernel/resource.c:337: warning: Function parameter or member 'first_lvl' not described in 'find_next_iomem_res'
  ../kernel/resource.c:337: warning: Function parameter or member 'res' not described in 'find_next_iomem_res'

Add the missing function parameter documentation for the other warnings:

  ../kernel/resource.c:409: warning: Function parameter or member 'arg' not described in 'walk_iomem_res_desc'
  ../kernel/resource.c:409: warning: Function parameter or member 'func' not described in 'walk_iomem_res_desc'
