Junjie Mao 004d2e2696 HV: treewide: give names to unnamed structs/unions
According to the syntax defined in C99, each struct/union field must have an
identifier. This patch adds names to the previously unnamed fields for C99
compatibility.

Here is a summary of the names (marked with a pair of *stars*) added.

struct trusty_mem:

    union {
        struct {
            struct key_info key_info;
            struct trusty_startup_param startup_param;
        } *data*;
        uint8_t page[CPU_PAGE_SIZE];
    } first_page;

struct ptdev_remapping_info:

    union {
        struct ptdev_msi_info msi;
        struct ptdev_intx_info intx;
    } *ptdev_intr_info*;

union code_segment_descriptor:

    uint64_t value;
    struct {
        union {
            ...
        } low32;
        union {
            ...
        } high32;
    } *fields*;

    similar changes are made to the following structures.
    * union data_segment_descriptor,
    * union system_segment_descriptor,
    * union tss_64_descriptor, and
    * union idt_64_descriptor

struct trace_entry:

    union {
        struct {
            uint32_t a, b, c, d;
        } *fields_32*;
        struct {
            uint8_t a1, a2, a3, a4;
            uint8_t b1, b2, b3, b4;
            uint8_t c1, c2, c3, c4;
            uint8_t d1, d2, d3, d4;
        } *fields_8*;
        struct {
            uint64_t e;
            uint64_t f;
        } *fields_64*;
        char str[16];
    } *payload*;
