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.
