Junjie Mao ef3cb5ba1c treewide: remove unnecessary unnamed structs/unions
According to the syntax defined in C99, each struct/union field must have an
identifier. This patch removes unnamed struct/union fields that can be easily
expressed in a C99-compatible way.

Here is a summary of structs/unions removed.

struct vhm_request:

    union {
        uint32_t type;                  uint32_t type;
        int32_t reserved0[16];    =>    int32_t reserved0[15];
    };

struct vhm_request_buffer:

    struct vhm_request_buffer {
        union {                         union vhm_request_buffer {
            struct vhm_request ...; =>        struct vhm_request ...;
            int8_t reserved[4096];            int8_t reserved[4096];
        }                               }
    }

 " This file includes config header file "bsp_cfg.h" and other
	hypervisor used header files.
	It should be included in all the source files."

Yonghua Huang 9b37e1464c add IO requrest 'req_buf' check before reference
This address maybe invalid if a hostile address was set
in hypercall 'HC_SET_IOREQ_BUFFER'.it should be validated
before using.

Update:
  -- save HVA to guest OS's request buffer in hyperviosr
  -- change type of 'req_buf' from 'uint64_t' to 'void *'
  -- remove HPA to HVA translation code when using this addr.
  -- use error number instead of -1 when return error cases.

Qi Yadong 8502c8eff3 io: remove pio emulation restriction
Currently, the serial log is printed through IO(0x3f8).
Secure World will print serial log by port 0x3f8. So
remove the ASSERT for Secure World booting.
