Tuya data type 2 read as 32 bit integer (instead of 16 bit)

[barbudor]

Description:

This is a follow up on PR #12115 (and discussion #12114)
as discussed here #12272

PR12115 addressed only the case of Active_Power > 2 bytes, but Total_Power is also impacted.
After careful reading it doesn't seem a problem to always read a DpId type 2 as 4 bytes and make this a general case instead of specific.
