iwlwifi: add IO function for continuous write of target memory
Add new IO function _iwl_write_targ_mem_words() to support
target memory write for a continuous area. It will return
error code -EBUSY if iwl_grab_nic_access() fails to indicate
the memory write does not be performed. Meanwhile the existing
function iwl_write_targ_mem() also been updated by using
_iwl_write_targ_mem_words() in a single word case.
