staging: vt6656: desc.h Remove typedef struct tagSMICHDRHead to new structure in...

To new structure.
typedef struct tagSMICHDRHead -> struct vnt_mic_hdr

This is only needed by rxtc.c so moved to rxtx.h

The new structure is the same size as the old but
contains the members as pointer referenced in
rxtx.c s_vFillTxKey
u8 id
	*pMICHDR = 0x59;
u8 tx_priority;
	*((u8 *)(pMICHDR+1)) = 0; // TxPriority
u8 mic_addr2[6];
	memcpy(pMICHDR+2, &(pMACHeader->addr2[0]), 6);
