platform/x86: mlx-platform: Fix item counter assignment for MSN2700/ComEx system

Fix array names to match assignments for data items and data items
counter in 'mlxplat_mlxcpld_comex_items' structure for:
	.data = mlxplat_mlxcpld_default_pwr_items_data,
	.count = ARRAY_SIZE(mlxplat_mlxcpld_pwr),
and
	.data = mlxplat_mlxcpld_default_fan_items_data,
	.count = ARRAY_SIZE(mlxplat_mlxcpld_fan),

Replace:
- 'mlxplat_mlxcpld_pwr' by 'mlxplat_mlxcpld_default_pwr_items_data' for
   ARRAY_SIZE() calculation.
- 'mlxplat_mlxcpld_fan' by 'mlxplat_mlxcpld_default_fan_items_data'
   for ARRAY_SIZE() calculation.
