bq2415x_charger: Fix style issues

I hate doing these style fixups myself, but I also hate inconsitent code.
Normally I just ask to resubmit the patch with the issues fixed, but N900
is special: I have a selfish interest in it. :)

-  Value resistor_sense is needed for for configuring charge and termination
-  current. It it is less or equal to zero, configuring charge and termination
-  current will not be possible.
-
-  Function set_mode_hook is needed for automode (setting correct current limit
-  when charger is connected/disconnected or setting boost mode). When is NULL,
-  automode function is disabled. When is not NULL, it must have this prototype:

-      void *data)
-
-  hook is hook function (see below) and data is pointer to driver private data

-
-  Board/platform function set_mode_hook return non zero value when hook
-  function was successful registered. Platform code should call that hook
-  function (which get from pointer, with data) every time when charger was
-  connected/disconnected or require to enable boost mode. bq2415x driver then
-  will set correct current limit, enable/disable charger or boost mode.
-
-  Hook function has this prototype:

-
-  mode is bq2415x mode (charger or boost)
-  data is pointer to driver private data (which get from set_charger_type_hook)
-
-  When bq driver is being unloaded, it call function:
-
-    platform_data->set_mode_hook(NULL, NULL);
-
-  (hook function and driver private data are NULL)
-
-  After that board/platform code must not call driver hook function! It is
-  possible that pointer to hook function will not be valid and calling will
-  cause undefined result.
