It's not convenient for us to support CPU feature in AArch64. So let's change it to an array first and add an enum as the index of the array for convenience. Since we will never access high 32-bits of ID registers in AArch32, it's harmless to change the ID registers in AArch32 to 64-bits.

Each ID field identifies the presence, and possibly the level of support for, a particular feature in an implementation of the architecture. [1] For most of the ID fields, there is a minimum presence value, equal to or higher than which means the corresponding CPU feature is implemented. Hence, we can use the minimum presence value to determine whether a CPU feature is enabled and enable a CPU feature. To disable a CPU feature, setting the corresponding ID field to 0x0/0xf (for unsigned/signed field) seems as a good idea. However, it maybe lead to some problems. For example, ID_AA64PFR0_EL1.FP is a signed ID field. ID_AA64PFR0_EL1.FP == 0x0 represents the implementation of FP (floating-point) and ID_AA64PFR0_EL1.FP == 0x1 represents the implementation of FPHP (half-precision floating-point). If ID_AA64PFR0_EL1.FP is set to 0xf when FPHP is disabled (which is also disable FP), guest kernel maybe stuck. Hence, we add a ni_value (means not-implemented value) to disable a CPU feature safely.

2. write the values in (index,value) list to KVM by write_list_to_kvmstate; In step 1, the values of constant system registers are not allowed to write to (index,value) list. However, a constant system register is CONSTANT for guest but not for QEMU, which means, QEMU can set/modify the value of constant system registers that is different from phsical registers when startup. But if KVM is enabled, guest can not read the values of the system registers which QEMU set unless they can be written to (index,value) list. And why not try to write to KVM if kvm_sync is true? At the moment we call write_cpustate_to_list, all ID registers are contant, including ID_PFR1_EL1 and ID_AA64PFR0_EL1 because GIC has been initialized. Hence, let's give all ID registers a chance to write to KVM. If the write is successful, then write to (index,value) list.

For example, ID_AA64PFR0_EL1.FP field and ID_AA64PFR0_EL1.AdvSIMD must have the same value, which means FP and ADVSIMD are dependent on each other, FPHP and ADVSIMDHP are dependent on each other. This commit introduces a mechanism for CPU feature dependency in AArch64. We build a directed graph from the CPU feature dependency relationship, each edge from->to means the `to` CPU feature is dependent on the `from` CPU feature. And we will automatically enable/disable CPU feature according to the directed graph. For example, a and b CPU features are in relationship a->b, which means b is dependent on a. If b is enabled by user, then a is enabled automatically. And if a is disabled by user, then b is disabled automatically.
