w1: support auto-load of w1_bq27000 module.
1/ change request_module call to zero-pad single digit
family numbers. This appears to be the intention of
the code, but not what it actually does.
This means that the alias created for W1_FAMILY_SMEM_01
might actually be useful.
2/ Define a family name for the BQ27000 battery charge monitor.
Unfortunately this is the same number as W1_FAMILY_SMEM_01
so if both a compiled on a system, one module might need to
be blacklisted.
3/ Add a MODULE_ALIAS for the bq27000.
