[PATCH platform-next v1 7/8] platform_data/mlxreg: Add presence register field for FAN devices

[Vadim Pasternak <vadimp@xxxxxxxxxxxx>]

Add new field 'reg_prsnt' to the structure 'mlxreg_core_data' to
provide the number FAN drawers equpped within the system. The purpose
is to allow mapping between FAN drawers and FAN rotors (tachometer),
since FAN drawer can be eqipped with a few rotors.
