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.
