[ 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.

Random kernel crash detected in TI CICD when regulator driver is added.
This is root caused to irq index increment being done twice causing
irq_data being allocated outside of the range.
- Rework tps6594_request_reg_irqs with correct index increment
- Adjust irq_data kmalloc size to the exact size needed for the device
This has been reported on TI mainline. No public bug report associated.

The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

This patch adds support for TPS6594 regulators (bucks and LDOs).
The output voltages are configurable and are meant to supply power
to the main processor and other components.
Bucks can be used in single or multiphase mode, depending on PMIC
part number.
