[ Upstream commit 2b06a1c889ca33d550675db4b0ca91e1b4dd9873 ]

Fix topology configuration for power supply units in structure
'mlxplat_mlxcpld_ext_pwr_items_data', due to hardware change.

Note: no need to backport the fix, since there is no such hardware yet
(equipped with four power) at the filed.
