util/spd_tools: Modify MT53E1G32D2NP-046 WT:B LPDDR4 config
CB:52586 ("util/spd_tools: Add MT53E1G32D2NP-046 WT:B LPDDR4 config") incorrectly set ranks per channel to 1. However, MT53E1G32D2NP-046 WT:B part has 2 channels per die and 2 physical dies. Each channel in each die shares DQ-DQS lines with the channel in other die and uses separate CS lines. Thus, number of ranks per channel is 2. This change fixes the attribute ranksPerChannel for MT53E1G32D2NP-046 WT:B in LP4x global config by setting it to 2.
