The global utilities block controls PCIE device enabling, alternate
function selection for multiplexed signals, consistency of HDA, USB
and PCIE, configuration of memory controller, rtc controller, lio
controller, and clock control. This patch adds a driver to manage
and access global utilities block for LoongArch architecture Loongson-2
SoCs. Initially only reading SVR and registering soc device are
supported. Other guts accesses, such as reading firmware configuration
by default, should eventually be added into this driver as well.

help
The Loongson-2's power management controller was ACPI, supports ACPI
S2Idle (Suspend To Idle), ACPI S3 (Suspend To RAM), ACPI S4 (Suspend To
Disk), ACPI S5 (Soft Shutdown) and supports multiple wake-up methods
(USB, GMAC, PWRBTN, etc.). This driver was to add power management
controller support that base on dts for Loongson-2 series SoCs.
