a39bd92e92 i2c: mux: mlxcpld: Add callback to notify mux creation completion
Add notification to inform caller that mux objects array has been
created. It allows to user, invoked platform device registration for
"i2c-mux-mlxcpld" driver, to be notified that mux infrastructure is
available, and thus some devices could be connected to this
infrastructure.

cae5216387 i2c: mux: mlxcpld: Get rid of adapter numbers enforcement
Do not set the argument 'force_nr' of i2c_mux_add_adapter() routine,
instead provide argument 'chan_id'.
Rename mux ids array from 'adap_ids' to 'chan_ids'.

The motivation is to prepare infrastructure to be able to:
- Create only the child adapters which are actually needed - for which
  channel ids are specified.
- To assign 'nrs' to these child adapters dynamically, with no 'nr'
  enforcement.

98d29c4104 i2c: mux: mlxcpld: Move header file out of x86 realm
Move out header file from include/linux/platform_data/x86/ to
include/linux/platform_data/, since it does not depend on x86
architecture.
