[ Upstream commit 74b38cd77d3eb63c6d0ad9cf2ae59812ae54d3ee ]
According to the TPS6594 PMIC Manual (linked) 8.3.2.1.4 Multi-Phase BUCK Regulator Configurations section, the PMIC ignores all the other bucks' except the primary buck's regulator registers. This is BUCK1 for configurations BUCK12, BUCK123 and BUCK1234 while it is BUCK3 for BUCK34. Correct the registers mapped for these configurations accordingly.
