The Hisilicon 6421v600 SPMI driver is ready for mainstream.
So, move it from staging.

Select IRQ_DOMAIN_HIERARCHY for pmic-arb in Kconfig since this driver
uses the version 2 IRQ interfaces. IRQ_DOMAIN_HIERARCHY selects
IRQ_DOMAIN, so it can be removed from here.

IRQ_DOMAIN is a hidden config option, so depending on it doesn't
make any sense. Select the config option because it's required to
compile this driver.

Qualcomm PMIC arbiter driver already depends on ARCH_QCOM,
which could be either ARM or ARM64. New version of the PMIC
arbiter controller is available on 64 bit platforms.
Remove ARM dependency to allow driver to be build for 64 bit
platforms.

With the split of Qualcomm MSM support into legacy and multiplatform,
the SPMI PMIC arb driver is only relevant on the multiplatform supported
SoCs. Switch the Kconfig depends to ARCH_QCOM.

The Qualcomm PMIC Arbiter, in addition to being a basic SPMI controller,
also implements interrupt handling for slave devices. Note, this is
outside the scope of SPMI, as SPMI leaves interrupt handling completely
unspecified.
Extend the driver to provide a irq_chip implementation and chained irq
handling which allows for these interrupts to be used.

Qualcomm's PMIC Arbiter SPMI controller functions as a bus master and
is used to communication with one or more PMIC (slave) devices on the
SPMI bus. The PMIC Arbiter is actually a hardware wrapper around the
SPMI controller that provides concurrent and autonomous PMIC access
to various entities that need to communicate with the PMIC.
The SPMI controller hardware handles all of the SPMI bus activity (bus
arbitration, sequence start condition, transmission of frames, etc).
This software driver uses the PMIC Arbiter register interface to
initiate command sequences on the SPMI bus. The status register is
read to determine when the command sequence has completed and whether
or not it completed successfully.

System Power Management Interface (SPMI) is a specification
developed by the MIPI (Mobile Industry Process Interface) Alliance
optimized for the real time control of Power Management ICs (PMIC).
SPMI is a two-wire serial interface that supports up to 4 master
devices and up to 16 logical slaves.
The framework supports message APIs, multiple busses (1 controller
per bus) and multiple clients/slave devices per controller.
