Note that in this older CMD-DB name format the SPMI bus on which a particular PMIC regulator exists was not apparent from its CMD-DB name. New targets like Glymur, where we have multiple SPMI buses, overcome this limitation by following a new CMD-DB name format: `^(L|S|B)[1-9][0-9]?[A-N]_E[0-3]$` Here `[A-N]_E[0-3]` part will now be read from the `pmic-id` DT prop and it includes the SPMI bus id `[0-3]` as well. However, the PMIC ID part `[A-N]` of the CMD-DB name is now unique only to the SPMI bus that the PMIC regulator is present on. which means `L1B_E0` and `L1B_E1` are both possible CMD-DB names for two different regulator LDOs present on two different SPMI buses (bus id 0 and 1) on the same board. Note that since the new `pmic-id` DT property is a combo of PMIC ID and SPMI bus ID, so its still unique to each PMIC present on the board. Update the `pmic-id` property pattern information to reflect this change in the driver handling to support this new CMD-DB naming format while maintaining backward compatiblilty with old CMD-DB naming format which is still supported for older/existing targets.
