x86/resctrl: Add missing resctrl initialization for Hygon

Hygon CPUs supporting Platform QoS features currently undergo partial resctrl
initialization through resctrl_cpu_detect() in the Hygon BSP init helper and
AMD/Hygon common initialization code. However, several critical data
structures remain uninitialized for Hygon CPUs in the following paths:

 - get_mem_config()-> __rdt_get_mem_config_amd():
     rdt_resource::membw,alloc_capable
     hw_res::num_closid

 - rdt_init_res_defs()->rdt_init_res_defs_amd():
     rdt_resource::cache
     hw_res::msr_base,msr_update

Add the missing AMD/Hygon common initialization to ensure proper Platform QoS
functionality on Hygon CPUs.
