TPS65215 is a Power Management Integrated Circuit (PMIC) that has
significant register map overlap with TPS65219. The series introduces
TPS65215 and restructures the existing driver to support multiple devices.

This follow-up series is dependent on:
Commit f84464ec8190 ("regulator: dt-bindings: Add TI TPS65215 PMIC bindings")
Commit 8206c20f4c82 ("mfd: tps65215: Add support for TI TPS65215 PMIC")
Commit 0e0b7f00c111 ("mfd: tps65215: Remove regmap_read check")

TPS65219 Cleanup Series:
GPIO: https://lore.kernel.org/all/20241217204755.1011731-1-s-ramamoorthy@ti.com/
MFD: https://lore.kernel.org/all/20241217204935.1012106-1-s-ramamoorthy@ti.com/
Reg: https://lore.kernel.org/all/20241217204526.1010989-1-s-ramamoorthy@ti.com/

- Both TPS65215 and TPS65219 have 3 Buck regulators.
- TPS65215 has 2 LDOs, whereas TPS65219 has 4 LDOs.
- TPS65215 and TPS65219's LDO1 are the same.
- TPS65215's LDO2 maps to TPS65219's LDO3.
- TPS65215 has 1 GPO, whereas TPS65219 has 2 GPOs.
- The remaining features are the same.

Change Log:
v2 -> v3:
- Correct gpio_chip.ngpio line to use .offset field
- Remove unnecessary newlines

v1 -> v2:
- have any PMIC lists be in alpha-numeric order: TPS65215, then TPS65219
- remove comma after terminator
- Add driver prefix to chip_data struct
