Unsupported for hipblas equivalent of Integer Datatypes.

[sriharikarnam]

The hipblas Datatypes equivalent is not supported for integer datatypes but supported in both rocblas and cublas.
list of rocblas datatypes not supported in hipblas
rocblas_datatype_i8_c
rocblas_datatype_u8_r
rocblas_datatype_u8_c
rocblas_datatype_i32_r
rocblas_datatype_i32_c
rocblas_datatype_u32_r
rocblas_datatype_u32_c

list of cublas Datatypes:

    CUDA_R_8I = 3,   
    CUDA_C_8I = 7,   
    CUDA_R_8U = 8,   
    CUDA_C_8U = 9,   
    CUDA_R_32I= 10,  
    CUDA_C_32I= 11,  
    CUDA_R_32U= 12,  
    CUDA_C_32U= 13   

where as hipblas only supports float datatypes as below
enum hipblasDatatype_t
{
HIPBLAS_R_16F = 150,
HIPBLAS_R_32F = 151,
HIPBLAS_R_64F = 152,
HIPBLAS_C_16F = 153,
HIPBLAS_C_32F = 154,
HIPBLAS_C_64F = 155,
};
